I've had a computer in some shape or form for too long to mention now, and have been building my own PCs for 20 years.Those two decades span multiple desktops, including some that were technically the same PC that evolved multiple times over years of upgrades.I'm also the designated tech person for a number of my family members and friends, which means I'm often saddled with old PCs that they don't know what to do with anymore.
And do you know what? I pretty much never throw them away.If they can be salvaged, they stay.And while it's not ideal for my storage space at home, it's given me so many different cool opportunities over the years that I can't see myself changing my mind about this anytime soon.
I didn't start hoarding PCs with any specific goal in mind It just happened, but now I'm glad Look, I didn't exactly set off on this journey of keeping many PCs with the goal of one day having, let's say, a dozen.But I was definitely reluctant to throw anything away, because when it comes to PCs, is more—you can't force your PC to run with a broken PSU, for example.Those older PCs have proven themselves to be worth their weight in gold simply because of the fountain of backup components they ended up being.
Plus, disposing of a PC properly is a bit of a chore, and wiping your data completely so that it can never be restored isn't easy, either, which made the idea of recycling those old computers even less appealing.Besides, there's plenty to be said in favor of these old PCs.They no longer have to be impressive.
Once it's no longer your main machine, the bar drops dramatically, and suddenly an old computer that gave you a minor headache can do all these jobs you almost didn't know you needed.That's how I ended up not just keeping my PCs, but also actively using them.Thermaltake LCGS Quartz i1460 Gaming Desktop $990 $1100 Save $110 If your old PC is starting to get on your nerves, give it a less taxing job and pick up this prebuilt to replace it.

An old PC can become a surprisingly handy thing.Some of the things you could use yours for include backups, and I do mean actual data backups.
With a couple of spare drives, your PC can be a local backup box, a basic NAS, or a place to store files you don't want to keep on your main PC.Such a PC can be extremely basic; it just needs to boot, stay connected, and have some storage.Quiz 8 Questions · Test Your KnowledgeDIY PC buildingTrivia ChallengeFrom socket types to cable chaos — test your knowledge of building computers from scratch.HistoryHardwareTroubleshootingQuirksTipsBegin 01 / 8HistoryWhat year did Intel release the first consumer processor that popularized the DIY desktop PC market — the Intel 8086?A1972B1975C1978D1981Correct! The Intel 8086 launched in 1978 and gave birth to the x86 architecture still used in PCs today.
It was a 16-bit processor running at 5–10 MHz — a far cry from today's multi-GHz giants.This chip laid the foundation for decades of DIY computing.Not quite — the Intel 8086 debuted in 1978.It introduced the x86 instruction set that still underpins virtually every desktop and laptop processor sold today.
IBM later used the cheaper 8088 variant for its first PC in 1981, which is sometimes confused as the origin point.Continue 02 / 8HardwareWhen building a PC, what does 'POST' stand for in the context of the boot process?AProcessor Output Self TestBPower-On Self-TestCPrimary Operating System TransferDPower Output Signal ThresholdCorrect! POST stands for Power-On Self-Test, a diagnostic routine your motherboard runs every time you boot up.It checks that critical components like RAM, CPU, and GPU are present and functional.If POST fails, you'll often get beep codes or LED indicators to help diagnose the problem.The correct answer is Power-On Self-Test.
Every time you press the power button, your motherboard runs POST to verify that essential hardware is connected and working.Failed POST is one of the first hurdles new PC builders encounter, often caused by unseated RAM or a forgotten power connector.Continue 03 / 8QuirksWhy do experienced PC builders recommend touching a metal part of the case before handling components?ATo warm up your hands for better gripBTo check if the case is properly grounded before installingCTo discharge static electricity from your bodyDTo magnetize your fingers for handling small screwsCorrect! Static electricity built up on your body can silently destroy sensitive PC components in an instant — a phenomenon called electrostatic discharge (ESD).Touching bare metal grounds you and neutralizes that charge before it can zap your CPU or RAM.
Anti-static wrist straps work even better for extended build sessions.The answer is to discharge static electricity.Your body can carry thousands of volts of static charge without you feeling a thing, but that invisible zap can permanently damage a CPU or RAM stick.It's one of the oldest and most important safety habits in PC building — cheap insurance for expensive parts.Continue 04 / 8TroubleshootingA newly built PC powers on, fans spin, but there's no display output.
What is the MOST common first thing to check?AReplace the CPU thermal pasteBEnsure the monitor is plugged into the GPU, not the motherboardCReflash the BIOS using a USB driveDCheck the SATA cables are firmly connectedCorrect! This is arguably the most common rookie mistake in PC building — plugging the monitor into the motherboard's video output when a dedicated GPU is installed.The motherboard's HDMI or DisplayPort is disabled by default when a GPU is present.Always connect your display directly to the graphics card.The most common culprit is having the monitor plugged into the motherboard's video port instead of the dedicated GPU.
When a graphics card is installed, most systems disable the motherboard's integrated video outputs automatically.It's such a frequent mistake that it has become a running joke in PC building communities.Continue 05 / 8HardwareWhat is the purpose of thermal paste when installing a CPU cooler?AIt acts as an adhesive to hold the cooler in place permanentlyBIt fills microscopic imperfections between the CPU and cooler to improve heat transferCIt insulates the CPU from electrical interference caused by the coolerDIt lubricates the cooler's fan bearings for quieter operationCorrect! Even finely machined metal surfaces have tiny imperfections and air gaps at the microscopic level.Thermal paste — also called thermal interface material (TIM) — fills those gaps to ensure maximum heat conduction from the CPU to the cooler.
Without it, air pockets act as insulation and temperatures can skyrocket dangerously.Thermal paste fills microscopic gaps between the CPU lid and the cooler's base plate.Metal surfaces may look flat and smooth, but at a microscopic scale they're riddled with tiny ridges and valleys that trap air — and air is a terrible heat conductor.A thin, even layer of thermal paste eliminates those gaps and keeps temperatures in check.Continue 06 / 8HistoryThe ATX motherboard form factor, which became the standard for DIY desktop PCs, was introduced by which company and in what year?AAMD in 1990BASUS in 1993CIntel in 1995DIBM in 1988Correct! Intel introduced the ATX (Advanced Technology Extended) standard in 1995, replacing the older AT form factor.
ATX standardized component placement, power supply connectors, and airflow direction — making DIY builds far more practical and interchangeable.Nearly 30 years later, ATX and its derivatives like Micro-ATX and Mini-ITX still dominate the market.ATX was introduced by Intel in 1995.It was a major leap forward from the previous AT standard, defining a common layout for motherboards, cases, and power supplies that made mixing and matching components from different vendors straightforward.
That standardization is a huge reason DIY PC building became so accessible.Continue 07 / 8TipsWhen installing RAM into a motherboard with four slots, where should you install two sticks to enable dual-channel mode on most boards?ASlots 1 and 2 (the first two slots nearest the CPU)BSlots 1 and 3, or slots 2 and 4 (alternating slots)CSlots 3 and 4 (the two slots farthest from the CPU)DAny two adjacent slots work equally wellCorrect! Dual-channel mode requires RAM to be installed in matched pairs on alternating slots — typically A2 and B2, or slots 2 and 4.This allows the memory controller to access both sticks simultaneously, effectively doubling memory bandwidth.Your motherboard manual will show the exact recommended slots, usually color-coded for convenience.To enable dual-channel mode, RAM should go in alternating slots — such as slots 2 and 4, often color-coded on the motherboard.
Placing both sticks in adjacent slots (like 1 and 2) forces single-channel operation, which can noticeably reduce performance in memory-intensive tasks.Always check your motherboard manual for the exact recommended configuration.Continue 08 / 8QuirksWhat is 'coil whine' in the context of a newly built gaming PC?AA rattling sound from an improperly secured case fanBA high-pitched noise produced by electromagnetic vibration in inductors under high electrical loadCThe sound of a CPU cooler fan spinning at maximum speed during stress testsDNoise caused by the hard drive's read/write head seeking data rapidlyCorrect! Coil whine is a high-pitched, sometimes whirring or buzzing noise caused by tiny electromagnetic coils (inductors) on a GPU or PSU vibrating at audible frequencies under heavy electrical load.It's technically a defect in manufacturing tolerances but is extremely common and not usually harmful to the component.
Ironically, it's often loudest in high-end GPUs under uncapped framerates.Coil whine is that annoying high-pitched squeal coming from inductors on your GPU or power supply vibrating under electrical load.It tends to be loudest when framerates are uncapped or during heavy computational tasks.While alarming to new builders, it's usually harmless — though some manufacturers will replace components with severe coil whine under warranty.See My Score Challenge CompleteYour Score/ 8Thanks for playing!Try Again A retired desktop can also become a media server, a living room PC, a garage computer, or a dedicated machine for smart home software.
Even if the computer has an ancient graphics card, you can turn it into a home entertainment center (also known as an HTPC).Many old PCs will still be more useful than just about any console because of platform flexibility and easy navigation.Plus, with Lossless Scaling, basically any PC can handle some not-too-demanding gaming.
There's more.You can use it for Linux experiments, old games, printer/scanner duty, or any little household tasks.Basically: share it across your entire home network instead of keeping it your own.
Having a spare PC is also a lifesaver for troubleshooting.It means you can always test various components, cables, adapters, and other peripherals without having to ask a friend to let you come over and test stuff on their PC.Sometimes the parts are more useful than the PC itself A spare component can save your whole day Sometimes, the PC itself doesn't need to survive as a complete system.
A spare SATA cable, case fan, PSU (a major one to have at home!), SSD, GPU, or even a bag of random loose screws can come in handy.Storage is probably the biggest one here, and I repurpose pretty much all of my drives, including tiny old SATAs.An old SSD or HDD may be too slow for your main PC, but can still be super useful as a backup.
I also like keeping a spare PSU, some sticks of RAM (expensive, I know), and a backup GPU at home.This is just stuff I've amassed over the years, and it's saved me time and time again in a pinch.The trick is knowing what not to keep I always err a bit too far on the side of caution When I'm faced with the decision of "keep" or "throw away," I always end up keeping way more stuff than I need to.
This doesn't appear to be true outside of my PCs and other electronics, though; I happily donate old clothes or books throughout the year, but I do tend to hold on to my PCs for ages and ages.Subscribe for smart tips on repurposing old PCs Join the newsletter for practical guides on turning retired PCs into backups, media centers, parts spares, or troubleshooting rigs, plus hands-on PC and home-tech tips to help you repurpose hardware instead of tossing it.Get Updates By subscribing, you agree to receive newsletter and marketing emails, and accept our Terms of Use and Privacy Policy.
