well, for me... I have 2 gigs of DDR400 I want to use up. I'm not thrilled with the SIs chipset based board, but I also don't plan on overclocking it. Coming with a cooler and a case, and even a PSU is an added bonus. I need a new case and this one looks decent.
I already have a 500Watt Ultra PSU from the FAR deal a few months ago. However, shipping on HSF's and PSU's and Cases really adds up fast if you dont buy it all together.
I'd have preferred an intel rig, but the cost of the motherboard and DDR2 would have spoiled it for me. An opty 165 also would have been nice, but then again, if I ever want to gain some extra performance, an FX-60 is multi-unlocked. Who knows how the SIS chipset is for overclocking though....
From what I read, these are pretty easy to hit 3.0 with.
