Thats too bad, I didnt think the thermal performance would be so terrible. I think what Antec needs to do, and they could make quite some money off this one, is update the Performance One line. This is what I would like to see in the P184: -Make it a little bit wider, so cable management behind the back panel becomes easier. -Make a large CPU cut-out on the back of the motherboard tray, for fitting coolers. -Give it USB3 support. -Make it a little bit taller, and add an additional 120mm fan mount or two so that you could place a dual or triple rad in the top WITH fans, all on the interior. With the case being made wider, these could even be 140mm mounts, though then the case would probably also need made longer. -Because PSU's are now more efficient than ever, and PSU heat affecting the rest of the hardware in the case is now negligible, remove the wall that separates the 'upper' and 'lower' chambers. I know this removes a key characteristic of the series, but it would allow for the case to have 8 expansion slots instead of 7, and separate chambers are now no longer much necessary.
