the first once can either have a fan on top or the usb junk.
I built a comp for a freind using that case, and I have to say it is the most difficult case I have had to work with. The one I used had the mounting holes for the 5 1/2" bays too low, so I had to dremmel them to make the screwes meet the holes. Otherwise, it is just a pain to work with.
2nd one by far. However, might wanna look at lian-li PC-V1000 or 2000 for real good air cooling. Short of running massive air, this is bar none best cooling case I've tried.
