about 6 months ago my dad built a new pc, it was quite well speced (2 Gb ram, 4000 AMD 64, 2x 6600 GT's), however, he will upgrade it and give the "old" one to me (as my pc is getting slightly old, and my mums is just ancient) on the condition i find him a new pc for under £1000 that works perfectly under Linux, he likes the extra ram (in fact he will keep his ram!), and says he needs no more than a 4000 AMD 64-bit CPU, but doesnt need the SLi at all, and would like something a bit slower from ATi, can anyone help?

EDIT - btw, he has the know how to build it himself

I called and talked to your dad. I gave him my recommendations and now he's giving ME his old PC. So, sorry bout your luck. Mine isn't all that bad, just needs a gfx card, but I'll set it up for the 5 yr old daughter. In the mean time, I'm sending you her old Celeron 667 PC to take the place of the PC I'm getting off your dad that you should have gotten. Enjoy!

Sorry, I don't know anything about Linux, so can't help out. Don't see any reason he would want to upgrade that thing!!!

the real reason he wants to upgrade is that my pc will cost a lot to upgrade as it is Socket A agp, so everyhing (bah ram and pheripherals) will have to be replaced
