My current Compaq 4 gig comp isn't gonna cut it anymore. My friend built a computer that he doesn't use at all and wants to sell it to me for 275 bucks. He said I definitely won't find a better computer for cheaper because he built it himself, and I don't know much about technical computer talk. Specs: 750mhz AMD duron processer 256mb ram 56x cd drive NIC card monitor Keyboard Windows XP Pro USB Ports Should I go for it? How much would this comp normally cost? He's a friend and wouldn't rip me off.
