Hey guys just wondering if anyone has unused PC parts that I could work out a deal on ?

Basically, what I'm after is a whole system to run as a server PC to host my CoD server and other server shit. The computer that I'm running now is a complete piece of shit, running an old ASUS AGP board (N) so it's no good at all.
The reason for it being 2nd hand parts is because I don't see the need in buying everything brand spankin new for a server PC. It only needs to last till the end of the year when I upgrade this PC into a monster and then I'll just use this PC as a server.

At the moment the parts I don't need are :
Case.
Power Supply.
Hard drive.
DVD player.

It doesn't need to be the latest and greatest, just something with a bit of power that has the option for upgrade eventually or easy to find parts if they die for whatever reason.(e.g PCI-E)

So it leaves me with wanting/needing:
Mainboard
CPU (hopefully already attached to the board but no biggy if it isn't)
Graphics Card
Ram to suit board

Cheers guys
