Check this thing of beauty out. I picked it up new on EBay for $71. It is a Lytron 6320 ALL COPPER heat exchanger (23"x12"x3.5" ... not an internal mount type) with 1/2" barbs, and the internals are made out of 1/2" copper tubing with copper fins (no thin tubes to severely hamper flow ... just a ton of switchbacks to mildly slow down the works, though it'll be no sweat with the pump I'll be using). It is coated with black anti-corrosive paint, and has a built in mounting bracket.

I'm probably going to use this bastid as a cooler for a multiple computer rack mount with centralized cooling I'm starting to gather stuff for. The BIX I'm using now will probably be used as an aftercooler on a secondary loop coming from my res (from the res -> Crap ViaAqua submerged -> BIX -> same res). I won't attact fans to the BIX ... it'll just be for drawing a little more heat out of the water. That is, if it even needs it after it all passes through this monster.
