I then insulated the back of the CDRW to prevent condensation. I also made sure it is water tight.
Fourth, I mounted the PSU. I decided to mount the PSU on the back of the freezer by the condenser. Submerging it would only add unnecessary heat. This picture is before adding the wire loom protector.
I had to extend the power wires 6 feet to reach the MOBO, pump, CDRW, and HDD. I cut a hole in the back of the freezer and ran the wires thru it. I did the same thing for the monitor, speaker, keyboard, mouse, and USB ports. I put 2 small pieces of wire loom around the VGA cable to protect it from the cut metal. Then, I sealed it with some silicon.
 
Fifth, I installed the AGP card, memory, CPU, and CPU heat sink with the pump assembly. Before I installed the CPU, I put some silicon in the CPU socket. Then, I placed it in the liquid containment unit (LCU) "modified 5 gal fish tank" I also filled up 3 Mason jars with water and froze them. I will put these in the LCU also. Why?, well, they saved me some money on the liquid and I figure it will help the surrounding liquid stay cooler.
Last but not least, I filled up the LCU and began freezing the pc. I turned the pc on when the liquid temp reached -4 F / -20 C.
Conclusion
So, what's the pay off? A super cooled, super fast pc. Here are some statistics:
CPU temp is 4.4 F
MOBO temp is -4 F
CPU is running at 2 GHz @ 380 MHz FSB
RAM is running @ 380 MHz.
I tried 400MHz, but the RAM took a dump on itself. I knew I should have bought the better stuff...
The CPU was at -22 F, however the pc would not turn on at that temp. I will need to study on that one.
Is it the fastest thing out there? No, that is not what this project was about. It is about conquering the temperature barrier and most importantly, having fun and learning. Besides, I wanted to show that submerging a pc and freezing it is relatively easy to do and does have to cost a small fortune. Buying the parts that I did and over-clocking them saved me about $160.00 for comparable AMD parts and about $200.00 for comparable P4 parts. Check out the for the ECM-2 DF.
The damage to the wallet wasn't bad either. It cost me about $800.00 for parts. That's including the freezer, which cost the most.
