Case: Apex MI 008
Power Supply:Seasonic 450W SFX12V
Processor:Intel CoreI5 2400

Hard Disk Drive:Samsung Spinpoint F3 1TB drive
The problems with your selected case are:
1) It only comes with a 250 watt power supply. In order to make it capable for gaming, I added the Seasonic 450W SFX12V PSU; the most wattage I could find in the SFX form factor.
2) That case is that it only has room for a single slot graphics card. Most newer gaming class graphic cards require dual slots for the cooling fan. I went with this PowerColor because the XFX was out of stock.
3) The case has no cooling. It was one side vent opposite of where the graphics card will be placed.
I *REALLY* cannot recommend using this case for a gaming system.
