Yo i was considering making a secondary cheapo PC as the old one died of old age...
Watching tomshardware.com always helps so based on their comment i compiled this component price chart that ill share with you:
warning you might not want to overclock the CPU and then u should seriously consider a better CPU (with more balanced fsb and all the secondary features this one lacks)
Also the nvidia card the deceased pc had was destroyed because of the fan getting completely brokenjust when the warranty expired (wich led to the core getting totally screwed) that explains the coice of card, you should consider a bigga one. all thats left is a case+powersupply and an HDD.
