What can you do with your old PC?

My PC went faulty, and I have few spares such as the Processor, Power Supply and RAM, etc.,

What can I do with it? I know I may well use them to build a new CPU. But, any other ideas or your experience in this..?!!

It fully depends on what particular component went faulty.

I have had self built 3 computers where the capacitors on the main bard went bad, and I was able to give it new life by several years - two of those are still in working order.

Also - some years ago I was tired of dropping support for windows (often equals trashing fully working hardware because windows cannot run on that) so I simply ditched Windows, switched to Linux.

Yes, Grossel . The nearby radioshack is not able to find whats faulty in the motherboard, but he does say that the repair is not possible.
