For those who want a drastically modded case, but don't want the hassle of doing it themselves, there is a lazy way out. If you'd like to know what I'm talking about here, then just head on over to Inside-Hardware and check out their review of the CS-INWIN ALASKA FT Computer Case. here's a snip:

"So how did the Computers Divine case compare after 3 weeks of constant use? To my amazement it absolutely destroyed my Addtronics in every way imaginable! The entire case was so quiet that one 90mm Delta fan in my Addtronics case was louder then all the fans in the Computers Divine! Even better, the Computers Divine case kept almost every component in my case 15-20 degrees cooler at all times! This is simply amazing. The way that they do it,is by using slow moving fans to keep the noise down, yet place them well enough, that cool air is always in every part of the case. Most interesting though, is the way they setup the CPU cooling. The Cold air enters from behind the case (I have never seen this done before) and is sucked back out through the power supply. Although, this was an unusual method, it worked out to become the best cooling design I have used."
