Case prep continued: Power Supply
The last step in case preparation is installing the
power supply. The thing to pay attention to here is
noise generation versus power output. Again, I took
Dave's advice and went with a Nexus 4000. While the
name sounds like a ship from Battlestar Galactica,
this one of the quietest rated PSU's on the market
having a noise rating of just over 20db. With a 400W
power rating, this PSU should have enough juice to
keep the main rig here in the 3DV dungeon running
full steam, even with the addition of cold cathode
lights and LED fans.

I wanted to see what the real difference was between
the Nexus and another "silent" power supply,
so I cracked it open. Well, what I found was a nice
quiet 80mm fan, and a giant heat sink. I opened
a Thermaltake Purepower supply that is here as well
for comparison. As you see, there is about half the
heatsink in the Tt, which is a fairly quiet PSU (although
by no means silent) Shuch a large heatsink would allow
more heat to dissipate with less air blowing past,
resulting in less noise.
Intstallation is as straight forward as it can get.
Hold in place.. add screws.. voila!
With the case almost ready to go, lets have a look
at fans...
