How to reuse an old PC: what to do with an old computer

Recycle your old computer at home. We offer twelve suggestions of what to do with an old PC

You've just bought a shiny new PC and you're wondering what to do with your old machine. Throwing it out makes you feel guilty as it's perfectly functional. You can do plenty of things with an old PC besides sending it to the recycling heap. Let's take a look at a few ways you might reuse an old PC.

5. How to reuse an old PC: Dedicate it to 'Distributed Computing'

Want to do a little good for humanity? How about dedicating your old PC to one of the various public distributed computing projects?

The best known is probably Folding@Home. Folding@Home uses computing resources from all over the world to help study protein folding, an essential element to understanding how many diseases operate. If your old PC has a fairly new graphics card, that hardware can often pitch in as well, and offer up even more computing resources. Other distributed computing ventures include:

6. How to reuse an old PC: Use it as a dedicated game server

Do you have a favourite multiplayer game? If so, check and see whether it's a game where you can host a server on a local computer - you might consider making your old system a dedicated game server. Most multiplayer games capable of playing online often support dedicated servers.

The great thing about many of these dedicated game servers is how little system horsepower they actually need. I ran a Freelancer server on an old Pentium 4 laptop system, at times supporting eight simultaneous users, with no performance issues.

7. How to reuse an old PC: Use it for old-school gaming

Related to the idea of using an older system as a dedicated game server, consider repurposing that box for old school gaming. You can go as nuts as you want. For example, install Windows 98, so you can run those older Windows 95 and DOS games, if you have some around. Note that this isn't as necessary as it used to be. Online services such as Steam are offering older games that have been rewritten to work under newer operating systems, and DOSBox lets you emulate a legacy DOS environment to get your classic gaming fix.

Perhaps the most complete site for older PC games is Good Old Games. GoG, as it's often called, offers a large number of older titles, all of which work fine under newer operating systems. So if you've always wanted to go back and play Planescape: Torment, now is your chance.

If you want to go really old school, install MAME (multiple arcade machine emulator) software. That will allow you to play arcade games and games written for older game consoles, provided you have access to the ROMs and other related files to run the games. MAME can become a gigantic time sink (albeit a very fun one), so you've been warned!
