AnandTech Review of Case
I have preordered the case. I like the change in design enough to see about it.
From the 3 different reviews I've seen and all the pictures I've looked over it is a well thought out ATX implementation of the BTX design. The case has been devided into three zones. The Hard Drive area, PSU area, and the upper case.
The Hard Drive area uses a direct 120MM intake fan to pull air in to cool hot drives. It then pushes the air out of the bottom of the case through the vents. The PSU area is designed for a 2 fan PSU, the bottom fan will pull air from underneith the case and exhaust it out the back. These two design points are important.
The Hard Drives contribute Heat to a System and they are usually put in the Air path of the intake fans. When the system usage is high and it heats the drives up, they in turn heat up the rest of the system. If only by 1-2 degrees C. The PSU's efficiency with power management will fluctuate as it heats up. So under heavy disk usage the hotter the system gets the move the voltage can vary, by isolating these two parts. It should improve the performance of the system. The only downside to this would be that you shouldn't remove the wheels if you don't like them. If you did, it will bake the hard drives and choke the PSU which will inturn would cook the CPU since all the hot air will rise.
Since system board is flipped upside down the CPU won't be the one baking under high usage it will be the video card, which is better able to handle the heat since it has more surface area to disipate that heat, both on the GPU die (larger then the P4 or the Athlon 64) and the Video Card PCB (larger then the CPU PCB). The CPU Heatsink (in a standard ATX case) sits in alot of heat from the rest of the computer infront of the exhaust fan and at the upper part of the case, which drops the heat transfer efficiency since the Delta is smaller there then outside the case (or even lower in the case). So the placement lower in the case and the removal of the heat from the Hard Drives and the Video card should help the CPU in overclocking.
The only thing I do not like about the case from what I've seen is that it doesn't include an additional CD cover. With all the other fore thought that went into the case it would seem only logical since this case was built for PC enthusiasts. The PC-V1000 should be much better at heat management then the rest of the ATX cases I've used and I hope to have it soon to confirm that.
