What should I do with my current PC when I get new one.

[Salsa Party Animal]

My PC will be replaced soon (Once I get new one)

It is Dell Pentium III 550 MHZ PC which have DVD writer, 80gigabyte hard drive and 17 inches monitor and 384 megabyte of ram.

Should I put it away or donate it to one of charity.

Probably give it away, to charity. It is probably worth peanuts.

You may be able to sell on the DVD writer and HDD for a few quid each though.

Personally I have my desk set up where I use my main PC for gaming, video, listening to music and the main stuff, and use my old machine so I can chat/web-browse etc while using my main machine, as well as storage of my files, downloading etc. Screens next to eachother.

You may have trouble losing the PC to charities other than those specifically dedicated to acquiring computers...PAT testing requirements are generally enough to make charities refuse electronics.

Don't forget to take measures towards securing your data should you get rid of the HD, there are cases of the 3rd world (that receives old computers from these PC charities) salvaging personal info and using it to commit fraud, let alone anyone else who may end up with the HD.

Well my folk will have it off me and use it more rather than laptop.

Would work well as a foot rest, coffee holder or a doorstop. But I heard you can extract gold from some of the parts.

Install www.slimdevices.com slimserver and get a squeezebox and xbox media center. Or something.
If you get rid of it, make sure you smash the HDD up. Or run Boot & Nuke - a nifty CD you can burn and when set to boot off your CD rom drive will quite happily destroy all the data on any writeable drives on your PC so there's no chance it can be recovered.
