Yeah, even if it is an ECS 'board, $45 shipped is a hell of a deal for an nForce2 mobo, CPU (that one a Barton or Thoroughbred core?), RAM, and video card (what model of GeForce?). I'd've jumped on it too. That board supports 200 MHz FSB - no multiplier or voltage adjustments though so I doubt you'll get near there. If it's a Barton core (512k L2) you've got a good shot at a bit over 2 GHz, though, no problem - say, 11.5x175 or so. Don't go too far, though, as the idiots soldered the damn BIOS chip down! Shades of their past, perhaps?
Don't mind me - I'm a Socket A geek.
