dude i so have one of these! well my custom is in this case... i have the motherboard for it though id say around 150-200, since its just an internet pc and workstation...
downnnerrrrrrrr.......the evo towers have no HD, RAM, GPU, or any sort of cards....all it has is the cpu, optical drive, PS, Mobo, and a nifty PCI card extender....heres a pic
I Have a lot of more parts, so i can probably source a 20 gig and sum pc133 for it, and a few pci cards
