I dont play WoW but i would suggest a AMD Athlon in the 2300+ range, $65, a mini tower Socket A mainboard, looking at about $55, Kingston 512MB PC2100 about $40, Decent 40GB HDD (western Digital, Seagate) $50 tops, Mini Tower Case, $40, DVD/CDRW drive $40(which is even overkill here you could feasibly jsut get a regular cd rom, or a CDRW only for $20 less. Total comes to $260 - $280 depending on components you find/deals you get. Thats not bad for a complete system, that is no where near outdated. Add your choice of vid card for like $50 - $150 depending on how much performance you really want, a Radeon 9250 256 will probably work absolutley fine and give you 30 - 60ish frames per second on that configuration. I dont know how cheap your looking to go, but this is a pretty happy medium, good performance, should load relatively quick and play pretty nice. Also, i dont usually suggest this but you might get lucky on a whole system, maybe dell or HP has some super hot deals going on, could check there too, but because its intended for gaming, steer clear of the celeron/duron range of processors, youll get frustrated.
