Quick Summary: What to Do With Your Old Computer
In a hurry? Here’s the short version of what to do with an old desktop PC:
- Working + reasonably modern? Sell it whole on eBay or Facebook Marketplace
- Got a decent graphics card or CPU? Part it out, the components often sell for more than the tower
- Working but slow? Install Linux, or repurpose it as a home server, NAS, or media centre
- Dead or ancient? Recycle it responsibly at a retailer or recycling centre
- Before any option: Remove or wipe every hard drive and SSD inside (desktops often have more than one)
- Never: Put it in the bin, it’s illegal in the UK under the WEEE Regulations
It’s usually under the desk, behind a stack of cables, wearing a thick coat of dust. That old desktop computer. The one you replaced with a laptop, or upgraded two Christmases ago, or inherited when a relative moved house. It still has a power light. You’re fairly sure it still turns on. And yet there it sits, doing absolutely nothing.
Desktop PCs are awkward in a way laptops aren’t. They’re heavy, they’re bulky, and most people have no idea what they’re actually worth. So they end up in lofts, garages and spare rooms, quietly losing value while taking up space.
Here’s the thing: that tower is probably worth more than you think, and you almost certainly shouldn’t bin it. Throwing electronics in your household rubbish is illegal in the UK under the WEEE Regulations. But beyond the legal side, an old desktop is two things at once.
It’s an opportunity, because desktop computers are modular. The graphics card, processor, memory and power supply can each be sold separately, and a well-specced GPU from a few years ago can still fetch a few hundred pounds on its own.
And it’s a responsibility, because that machine almost certainly holds your data. Desktops often contain two or three drives: a fast SSD for the operating system and a big hard drive for photos, documents and downloads. All of it can be recovered by someone with free software, even after you’ve “deleted” it. That’s why secure data destruction matters before anything leaves your house.
This guide walks through everything you need to know about parting ways with an old computer in the UK, whether it’s a gaming tower, an office PC, or an all-in-one. Let’s turn that dusty box into something useful.
Which Old Computer Option Is Right for You?
Before we get into the detail, let’s work out what makes sense for your machine. With a desktop, your best option depends on three things.
Does It Still Work?
- If yes: You’ve got every option, sell it whole, part it out, repurpose it, or donate it.
- If it powers on but is faulty: The components are very likely still worth selling, and the case, power supply and drives can be reused.
- If it’s completely dead: Computer recycling is the route, though working drives and graphics cards can often still be salvaged for cash first.
What’s Inside It?
- A dedicated graphics card (GPU): This is usually the single most valuable part. Even a five-year-old gaming GPU can sell for £80-£300.
- A recent processor and DDR4/DDR5 memory: Worth selling as a bundle to PC builders.
- Just integrated graphics and an old CPU: More suited to donating, repurposing or recycling than parting out.
What’s Your Priority?
- Maximum cash: Part it out on eBay or sell components on enthusiast forums
- Minimum hassle: Sell the whole tower on Facebook Marketplace or use a trade-in service
- Helping others: Donate to a charity that refurbishes computers for schools and families
- A fun project: Repurpose it as a home server, NAS or retro gaming machine
- Environmental impact: Make sure it goes to a certified recycler
Option 1: Sell the Whole Computer
If your desktop still works and isn’t ancient, selling it as a complete system is the simplest way to get money back. Plenty of buyers want a ready-to-go PC for the kids, a home office, or a first gaming machine.
Sell Privately (Most Money, More Effort)
eBay is the obvious home for a complete PC, though couriers charge more for a heavy tower, so factor that in. Take clear photos, list the exact specification (CPU, GPU, RAM, storage), and run a quick benchmark screenshot to reassure buyers.
Facebook Marketplace is ideal for desktops precisely because they’re awkward to post. Local collection means no shipping headaches. Always meet in a public place or have someone with you for a home collection.
Trade-In and Buy-Back Services (Less Money, Zero Hassle)
- Currys – Trade-in and recycling, though desktops fetch less than laptops
- CeX – Will buy complete desktop systems in-store for instant cash or credit
- Local PC shops – Many independent repair shops buy working systems to refurbish and resell
What Can You Expect to Get?
- Modern gaming PC (recent GPU, 3-4 years): £400-£900
- Mid-range office desktop (3-5 years): £100-£250
- All-in-one PC (e.g. iMac, 4-6 years): £200-£500
- Older tower with integrated graphics (6+ years): £40-£90
- Branded business desktop (Dell, HP, Lenovo SFF): £60-£150
Option 2: Part It Out (Often the Most Profitable)
This is the desktop owner’s secret weapon, and the biggest difference from a laptop. Because a PC is built from standard, swappable components, selling the parts individually frequently earns far more than selling the whole machine. Builders and upgraders are always hunting for specific bits.
The Parts Worth Selling
- Graphics card (GPU): Almost always the star. Check the model number on the side of the card and search “sold” listings on eBay for a realistic price.
- Processor (CPU): Intel Core and AMD Ryzen chips hold value well. Sell with or without the motherboard.
- Memory (RAM): Matched DDR4 or DDR5 kits sell quickly.
- Power supply (PSU): A good-quality 80 Plus unit is always in demand.
- Storage: SSDs sell well, but only after a secure wipe (see the data section below).
- The case: Even an empty case with working fans has buyers.
A Quick Reality Check on Prices
Always search completed and sold listings, not active ones, to see what items actually fetch rather than what hopeful sellers are asking. A tidy, accurately described component with clear photos will always outsell a vague listing.
One golden rule: never sell a drive without destroying the data on it first. We cover exactly how to do this further down.
Option 3: Donate to a Good Cause
A working desktop you no longer need could be exactly what a struggling family, a school, or a community project is crying out for. Digital poverty is a real and growing problem in the UK, and a refurbished PC can genuinely change someone’s prospects.
UK Charities That Want Your Computer
- Computers 4 Charity – Refurbishes and redistributes donated computers, free collection available
- WeeeCharity – Free UK collection, data wiping included, machines refurbished or responsibly recycled
- The Turing Trust – Sends refurbished computers to schools in sub-Saharan Africa
- IT Schools Africa – Accepts working desktops to support education overseas
Before You Donate
Wipe your data first, even though most reputable charities also wipe machines on arrival. Their mission is education, not data security, so the responsibility is yours. Include the power lead and a keyboard and mouse if you can spare them, as it makes the machine immediately usable.
Option 4: Repurpose It Into Something Useful
This is where desktops really shine. A tower has space, expandability and a proper power supply, which makes it a far better candidate for projects than a cramped old laptop. Here are eight genuinely useful second lives for an old computer.
1. A Home Media Server (Plex or Jellyfin)
Load up Plex or the free, open-source Jellyfin, fill it with films and music, and stream to every TV and phone in the house.
2. Network Attached Storage (NAS)
With a couple of hard drives and free software like TrueNAS, an old tower becomes a central backup hub for the whole family, no monthly cloud fees required.
3. A Linux Machine That Feels New Again
A lightweight Linux distribution such as Linux Mint or Lubuntu can make a sluggish old PC feel quick again, perfect for web browsing, email and homework.
4. A Retro Gaming Rig
Older hardware is brilliant for emulating classic consoles and running the games of the 90s and 2000s that don’t need a modern graphics card.
5. A Home Automation Hub
Run Home Assistant to control smart lights, heating and security from one local, private server.
6. A Dedicated Kids’ Computer
Set it up in a shared space with parental controls for homework and supervised browsing, keeping the family laptop free.
7. A Home Office or Print Server
An always-on machine can host shared files and printers for a home business without relying on the cloud.
8. A Learn-to-Tinker Machine
Because desktops open up so easily, an old one is the perfect, low-stakes machine for learning to upgrade RAM, swap drives and understand how a PC actually fits together.
Option 5: Recycle It Responsibly
If your computer is dead, genuinely ancient, or simply not worth selling, recycling is the right and legal choice. A desktop is full of recoverable materials, copper, aluminium, steel, and small amounts of precious metals, that should be reclaimed rather than buried.
Retailer Take-Back
Under the WEEE Regulations, retailers that sell electrical goods must help you recycle the old equivalent. Many large stores offer in-store drop-off points for old electronics, even if you didn’t buy the new item from them.
Council Recycling Centres
Every local authority runs a Household Waste Recycling Centre that accepts computers free of charge. Find your nearest via the RecycleNow locator.
Free Collection for Multiple Items
If you’re clearing out several machines, perhaps after an office move or a house clearance, a specialist recycler is far easier than multiple trips to the tip. Innovent’s computer recycling service offers free UK collection, accepts working and dead equipment, and provides certified data destruction with documentation if you need it.
How to Wipe Your Data Properly Before It Leaves
This is the bit most people get wrong, and with desktops it matters even more, because there’s usually more than one drive inside. Deleting files doesn’t actually delete them. Emptying the recycle bin doesn’t either. Even a factory reset can leave data that’s recoverable with free software. For the full picture, read our complete guide to hard drive destruction.
First, Find Every Drive
Open the case and look. Desktops commonly hide:
- A small M.2 SSD slotted flat onto the motherboard (easy to miss)
- A 2.5-inch SSD in a bay or stuck to the case
- One or more 3.5-inch hard drives in the drive cage
Account for all of them before you sell, donate or recycle the machine.
Method 1: Windows Factory Reset (Good)
For a working PC you’re selling or donating, this is usually enough. Go to Settings > System > Recovery, choose Reset this PC, then Remove everything, and crucially turn on the Clean data option. This overwrites the drive and makes casual recovery very difficult. Note that this only cleans the system drive, so secondary drives need wiping separately.
Method 2: Secure Erase Tools (Better)
For extra peace of mind, use dedicated software. DBAN (Darik’s Boot and Nuke) wipes entire hard drives from a USB stick, while Eraser overwrites individual files and free space in Windows. For SSDs, use the manufacturer’s secure-erase utility (Samsung Magician, Crucial Storage Executive and similar), because standard overwriting doesn’t reliably reach every cell on solid-state drives.
Method 3: Physical Destruction (Best for Sensitive Data)
If a drive held genuinely sensitive information, financial records, business data, anything you’d hate to leak, physical destruction is the only cast-iron guarantee. The big advantage of a desktop is that drives are easy to remove: undo a couple of screws, unplug two cables, and the drive is out. From there you can drill through a hard disk’s platters, or for total certainty use a professional service. Innovent’s certified data destruction shreds drives to HMG Infosec Standard 5 and issues a certificate of destruction for your records.
Before You Wipe Anything
- Back up any photos, documents or licences you want to keep
- Sign out of and deauthorise accounts (Microsoft, Adobe, Steam, iTunes)
- Remove the machine from your Microsoft account device list
- Don’t forget data hiding in card readers or connected USB drives
What You Should Never Do
Now you know what to do, here’s what to avoid. Some of these seem obvious, yet they’re surprisingly common.
Don’t Bin It
Throwing a computer in household waste is illegal in the UK under the WEEE Regulations. Hazardous materials end up in landfill, valuable metals are lost, and your data isn’t destroyed.
Don’t Sell or Give It Away With the Drives Still In It
This is the single biggest mistake desktop owners make. Always wipe or remove every drive first, even if you trust the recipient. Machines get resold, lost or stolen down the line.
Don’t Let It Rot in the Loft
Components degrade, capacitors fail, and the resale value of that graphics card drops every single month. If you haven’t used it in a year, it’s time to act.
Don’t Assume It’s Worthless
Even a “dead” PC often has a perfectly good graphics card, power supply or set of drives inside. Check before you write it off entirely.
Don’t Ignore Any Old Batteries
The small silver coin battery on the motherboard is fine, but if your machine is an all-in-one or has any lithium cells, those should be removed and recycled separately at a battery collection point.
Why 2026 Is the Year to Deal With It
Windows 10 End of Support Has Arrived
Windows 10 reached end of support in October 2025. Millions of perfectly capable desktops can’t upgrade to Windows 11 because of its TPM 2.0 and CPU requirements. If that’s your machine, you have a clear choice: install Linux to keep it secure and useful, donate it, or recycle it. A desktop running an unsupported, internet-connected operating system is a genuine security risk, so don’t leave it limping along online.
Component Prices Make Parting Out Worthwhile
Sustained demand for graphics cards and memory means second-hand component prices have stayed surprisingly firm. That old gaming tower could be funding a chunk of your next upgrade rather than gathering dust. Read more in our 2026 guide to recycling IT equipment.
Frequently Asked Questions
What is the best thing to do with an old desktop computer?
It depends on its condition and what’s inside. If it works and has a decent graphics card, parting it out on eBay usually earns the most. If it’s a tidy working system, sell it whole or donate it to a charity like Computers 4 Charity. If it’s dead, use responsible computer recycling. Whatever you choose, wipe or remove the drives first.
How much is my old PC worth?
It varies hugely with age and specification. A modern gaming PC might fetch £400-£900, a mid-range office desktop £100-£250, and an older tower with integrated graphics £40-£90. The graphics card alone is often worth £80-£300. Search “sold” listings on eBay for your exact components to get a realistic figure.
Can I just put my old computer in the bin?
No. Under the UK’s WEEE Regulations, computers must be disposed of properly. Council recycling centres accept them free of charge, retailers must take back old electricals, and specialist recyclers offer free collection. There’s no legitimate reason to bin one.
How do I wipe a desktop computer before selling it?
First, find every drive (desktops often have an M.2 SSD plus one or more hard drives). For a working machine, use Windows’ Reset this PC with the “Clean data” option enabled on the system drive, and wipe any secondary drives separately. For sensitive data, use a tool like DBAN or have the drives professionally shredded with certified data destruction.
Is it better to sell a PC whole or in parts?
Parting out usually earns more, sometimes considerably more, because builders pay a premium for specific components like graphics cards, processors and memory. Selling whole is faster and easier but fetches less. If your machine has a desirable GPU or recent CPU, parting it out is worth the extra effort.
What can I do with a really old or dead PC?
If it powers on, salvage and sell the graphics card, power supply and any working drives (after wiping). If it’s truly dead, take it to a council recycling centre or use a free IT recycling collection. Even non-working computers have value to recyclers for materials recovery.
Can I repurpose an old computer as a server?
Absolutely, it’s one of the best uses for an old tower. Free software like Jellyfin turns it into a media server, TrueNAS makes it network storage, and Home Assistant runs your smart home. Desktops have the space, power and expandability that laptops lack.
Do I need to remove the hard drive before recycling a computer?
It’s the safest approach. Either wipe the drive thoroughly first, or physically remove it (easy on a desktop, just a couple of screws and cables) and keep it until you can destroy it. If you use a certified recycler such as Innovent, they can shred drives for you and provide a certificate of destruction.
