Case and power supply look awesome but why not so high on the power supply. You only need double of the power the system will actually top out at. You add the componants total power draw and times that number by 2. Anything else is overkill. Heres an intresting article to back that up. "
So How Much Power Do I Need?
Obviously, we do not expect everyone to have all the terms of art down pat when it comes to power supplies. As you check out our power supply web pages you will notice these products come in a number of wattage designations. How much power is necessary for the “average� PC system, if there is such a thing nowadays? Take a look at what you’ve had in the past. If you bought a standard power supply from one of the top computer manufacturers, chances are you purchased a 250- to 300W power supply of average quality. Now that is more than enough for your run-of-the-mill system consisting of a hard drive, an optical drive and a fair-to-middling graphics card. However, if you are going to add more peripherals you need to seriously consider upgrading your power supply.
For your reference, following is a chart that illustrates approximately how much wattage you will need to run various common components in a PC system:
Component Wattage Required
Motherboard 15-30
Low-end CPU 20-50Â
Midrange to high-end CPU 40-100Â
RAM RAM 7 per 128MBÂ
PCI add-in card 5Â
Low to midrange graphics board 20-60Â
High-End graphics board 60-100
IDE hard drive 10-30
Optical drives 10-25Â

I only pasted the part that applies to this directly. There is more on this if you wish to read the entire article.

Hope this helps a bit.
