I will decide on PSU once I get some hint on the case.
As you can see, the graphics card (Radeon 5870) is pretty long (11.1 inches) and is the main constraint while deciding for the case. I have chosen following for case options. Please suggest which will be offering best value and will comfortably fit all the above mentioned components. If you know of some other SFF cases that would be good for this card, please suggest them as well. Here are my shortlisted options:
Silverstone SG07 (Comes with Power supply) L X B X H: 13.78 x 8.74 x 7.48
Apevia X-Q Pack 2 (Comes with 500W PSU) LXBXH: 14.70" x 11.20" x 9.00"
APEx TM series
Aerocool QX-2000 LXBXH: 15.4 x 11.8 x 9.45
NZXT Vulcan LXBXH: 16.00" x 7.00" x 16.60"
Thermaltake LANBOX Lite 16.9 x 9.1 x 11.8
CM Elite 341 LXBXH: 15.75" x 7.28" x 14.37"
Silverstone TJ8 LxBxH: 14.88" x 7.68" x 15.00"

Sugo S07 is obvious choice, but it is a bit expensive. So please give your thoughts on other options as well.
