I'm starting this worklog a few weeks late (forgive me, I didn't have batteries for my camera!), so I guess that I'll catch you guys up. I got a new computer, and I kind of wanted to get into overclocking/watercooling. It occured to me that without some sort of other cooling, you can never get get below ambient temperature! I started shopping immediately for a mini-fridge. I ended up buying a peltier-based 1.5L one off of ebay that was conveniently about as wide as my computer. I am now mildly kicking myself because I didn't do my homework and ended up paying about $30 too much (peltier units without a housing are like $5). Oh well.
I also bought a heap of other water cooling equipment, about half of which I will not use in this project. I'm not too worried about that, as I have a client who wants water cooling so I'll get reimbursed.
I also wanted a reverse atx case, so I flipped it upside down and cut out holes where they should be. I'll probably put in a 140mm fan in that gaping hole in the front so my case isn't so rediculously negatively pressurized.
I also cut a couple 90mm fan holes in the top. Here's the front after being cut:
I plan on using the fridge as a radiator on top of the case like such:
and using the other water cooling system as a secondary radiator/pump/resevoire in the back of the case where the fan mounts.
I have a submersible pump that I got from a little fountain thing that I found by the side of the road . I'll use that inside the fridge, which will remain about half full at all times. I was going to put the heatercore from the picture inside of it and air cool it, and then I decided that I would water cool the radiator, then I realized that would be a bit redundant, having water flow through water and all.
I also saw the dual-power supply mod, so I went and took one of my dozens of 300-watt and stripped non-necessary cords (everything but molex). I'm kind of kicking myself for cutting the P4 connector, as the fridge takes 12v dc and only runs at 5 amps. It's okay, I'll just run one of the mini connectors back up through and re-wire. I cut two holes in the top of the case for the wires and for the vent.
This top half, on the other hand, is rediculously positively pressurized. I'll probably lift the fridge to leave more room for airflow from the dual 90mm's. I'm thinking of either leaving the back of the case open, making a diaganol bend to accomadate power cord and air, or just sealing it off and rerouting the plug to the back. I'm not sure if I should add a front vent for more letoff the the pressure caused by the 90mm's, or if I should leave it closed to route the air past the heatsink of the peltier, because that thing gets HOT. Nothing bad will happen if it gets too hot besides it not cooling the water, but still.
