I recently bought one of these cases (Superpower KS-299xp) from crazypc.com after seeing it in a local store who happened to be out of stock on the item. I bought the case with an Enermax EG351P-VE(FC) 330 watt power supply. In addition to the fans in the power supply and at the front of the case, I added an "Evercool" 80mm rear exhaust fan that I pulled from my parts pile.
Noisewise, the case is perhaps a tad quieter than average due to the heavy plastic side panels -- but the difference isn't great. The construction quality is high, and the case is quite heavy.
I have an AMD Duron 750@900 (1.775v) on an Epox 8KTA3 with a cheap, relatively low-powered "AVC" heatsink. I suspect that this is a "hotter" combo than the P3-550 that Anand used while reviewing the case.
I haven't seen the 39C (102F) case temperatures that Anand mentioned. The highest I've seen so far is 32C (~89F), with an ambient temperature of about 74F. But I've only had the case for a week.
The cooling is definitely more than adequate for my needs. It'll be even better when I replace the cheap heatsink, although that's not really related to the case performance.
