Hello; I just wanted to second the P182, I also work with both of the cases, and find the Nine Hundred noisy compared to the P182. I have an OCZ GameXstream 700W, and was able to fit it perfectly, and even run the cables behind the motherboard tray (ALL OF THEM!!!). All in all, the P182 makes for a sweet build. I would recommend giving yourself a couple hours to build it, bring lots of tie-straps, and make it really nice. I'll try to include some pictures of my build after these words...
Have Fun!

Edit: Okay they are HUGE pictures, so I will take them down soon due to myself hosting this web server off this machine, and I am trying to game, omg. If you want to see my build just download the .RAR from my website, that way everyone that hits this forum doesn't download this stuff. Link is:

I looked at your pictures. Nice setup but I noticed your big speaker near your computer. I hope the magnet will not interfere with your HD!
