These are some links and thoughts I thought I would share with you. This is not exact science. Fell free to voice your opinions or other useful links.

To calculate your power supply requirements, go to:

http://www.extreme.outervision.com [...] orlite.jsp (Power supply calculator)

and add one Hard Disk (two for Raid), one optical drive, video card and CPU, use high end motherboard,
calculate Watts and divide by 12 to get amps on 12v rail. Add 15% or 2-4 amps for safety.

Subtract 10% from combined total for maximum amperage of PSU on 12v rails for aging
Compare your power supply combined 12v rail minus 10% to your requirements.
Combined rail should not exceed requirements.

I've seen most of these scattered around the forums, so it's nice of you to put them all together.

Like i see, the $799 will be a good deal if have monitor, keyboard and mouse. Or spend a little more and build yourself.
