Well im selling my old computer due to me building a replacement. The specs are:
Amd 3000+ Barton core
1.5gb of ddr, 1 stick is pc3200 and that 1 is crucial i believe, the other 2 are a random make and are pc2700, an overclock will sort the declocking.
Motherboard: asus board but cant remember model at this time so as soon as i build it into a new case i can tell you.
Gfx card: radeon 9600XT overclocked and its a sapphire card
Case: tsunami case, thats all i know.
Hard Drive: 80gb ide hard drive +20gb one, both maxtor
This computer has been great when i built it and the only reason i needed to upgrade was to play crysis.
I think somewhere around £55 is good, or nearest offer. Any questions post here or pm me, ill get photos soon.
