That's how much I can get it for Brand New.
But when its old, only worth perhaps 80-90% of of new value, there you have maybe 799.
Trent, for $1500, I can buy an Athlon XP 2800+, Asus Nforce 2 motherboard with 1GB of PC3200 and 250GB of HD and Radeon 9500 hacked into Radeon 9700 PRO. $1500-2500, very ridicous price.
