Yea, it would probably better if I posted it here
You can tell most of the design from the pics I think. I got the radiator for free from my local recycling center; it probably came out of a large dehumidifier or something. I salvaged those fans out of some old all in one Mac LCs, the metal cages were already on them.
I attached the fans to the radiator with a large piece of sheet metal and some sheet metal screws. I used a jigsaw to cut 4 92mm holes in the sheet and folded the edges over the sides of the radiator to form sort of a hood that makes sure all the air is focused to the radiator.
The fans are powered by a 12v ac adaptor (wall wart) that I had laying around. My neighbor gave me the pump; it turned out to be decent enough to keep a good amount of flow going even in that big of system (beckett M200, 185gph pond pump, 110v ac).
Skippy peanut butter jars make damned good reservoirs. I searched and searched for a jar that was just the right size for my pump. As I was eating some crackers and peanut butter one day I sat there staring at the Skippy jar and noticed the top would probably be large enough for my pump to fit in it. I enlisted my whole family to eat peanut butter and soon enough I had an empty jar to work with. Sure enough my pump fit in it perfectly. I then cut holes in the lid for the various tubes and power cord. Here is a pic of what it sort of looks like: <A HREF="http://www.folken.net/pics/mymachine/lid1.JPG" target="_new">test lid</A>. Bec the power cord needed that slit there it made the lid loose all ability to keep a good seal. So I just bought a big hose clamp and that took care of the problem. My outdoor jar has a 3rd hole in it for filling that I just cover with a piece of duck tape
The radiator is attached to my house from a couple wood screws on the top and a little right angled piece of metal on the bottom. That one beam on the top is there so that the radiator sits about 2" off the side of the house, that allows adequate air flow. It sort of looks like it is flush with the house in the pic but it defiantly isn't.
The Skippy jar is held in place simply by one big hose clamp and a piece of wood I screwed to a roof frame.
All hose connections on the system are sealed with blue silicon and hose clamps. There is about 30ft of tubing between the radiator and the comp, about 15ft there and back. The tubes and wires just drape along the walls to the computer. I made a long skinny piece of wood with 3 holes in it and put it in my window frame. 2 holes for the tubes and 1 for the power cords. This allows the stuff to easily enter my room and still allows me to close my window. For convenience sake I put quick release self sealing fittings on the computer side of the system so it would be easy to unhook it for maintenance or something.
