Oops a bit late but here goes
Just this weekend I purchased a new case to replace my Antec 300 (nothing wrong with it though)
For a very good price I got the Raidmax Super Altas:
Link (yes, I got the blue one )
In terms of cooling it only has the one fan at the back but this is easily matching the 2 fans I had on the Antec plus you can add 2 x 80mm or 1 x 120mm fan onto the top and fit another one in front of the hard drives.
I am also replacing my Cooler Master V8 since it's 5mm too big to fit in properly, and I am upgrading to a Corsair H55 which was very reasonably priced.
This is a pic of where I keep my PC:
LinkThere's a good 30cm between the back of it and the wall and at the time the side panel was off but it's on now and it's perfectly fine. It's a small room but there's a window above and behind the PC so I can get some good airflow going.
Specs:
CPU: AMD FX-8320
Motherboard: Gigabyte 970A-UD3
Graphics: Sapphire HD 7870
Cooling: Cooler Master V8 (replacing with Corsair H55)
PSU: Raidmax RX-1000AE
RAM: G.SKILL Ripjaws 8GB @ 1600MHz
EDIT: Forgot to add that the fan is very quiet compared to the Antec 300
Also it's easy to keep the cabling tidy, here's another pic:
