The main noise maker was the power supply. I ordered the TX650W power supply from Corsair. 5 stars.
I also disconnected all three of the cheap fans that came with the Antec case, and replaced them with one Scythe S-FLEX SFF21D 120mm Case Fan.
Now that the computer is pretty much silent, I want to make sure it's not going to over heat.
After doing some research, LM-Sensors seems to be the foundation for temperature sensing apps in Ubuntu. Once LM-Sensors is installed you should be able to run the command, sensors and get an output like the following:
~$ sensors

fan5: 463 RPM (min = 1155 RPM, div = 16) ALARM
Sys Temp: +50.0°C (high = +4.0°C, hyst = +15.0°C) ALARM sensor = thermistor
CPU Temp: +37.5°C (high = +80.0°C, hyst = +75.0°C) sensor = diode
AUX Temp: -25.0°C (high = +80.0°C, hyst = +75.0°C) sensor = thermistor
cpu0_vid: +0.000 V
One gotcha I encountered was getting Lm-Sensors to work with an Asus motherboard.
Originally when I tried the sensors command I got the following output:
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
After some more digging I found this fix:
~$ sudo modprobe w83627ehf force_id=0x8860
