OMG. My eyes

Seriously, Acrylic for a power supply is not too wise.
Think of the fire implications. That is placing a "fuel
load", right next to a source of heat, and with a fan
to feed fresh air to it, should burn real nice.

You didn't state what processor you had, so I'll assume
the most power hungry processor possible. This one is
103W. 103W/12V * (1/0.90) = 9.54 amps.

Radeon 9700 Pro. Power consumption here is 54W.

I can only compare it to a 9800 Pro, to get some idea of
how the power splits. That generation of cards seems to
use more 5V than 12V power. Less than 1A of 12V.

http://www.xbitlabs.com/articles/video/display/ati-powercons_8.html

Allocate 0.5A for fans. 2*0.5A for two hard drives.
1.5A for CD/DVD drive.

Total: 9.54A + 1A + 0.5A + 2*0.5A + 1.5A = 13.5A.

A power supply with 25A on 12V, should have no trouble
with a 13.5A load from the computer. The 5V @ 38A is
going to have no problem running the video card.
Now, just get one without the acrylic on it
