since pic I've got the radiator on its side now so it is below the water level of the bucket, and now with a pump and loop just for the radiator, get much higher flow for the whole system and a lot easier to bleed.
a cut down 19" industrial rack, now on wheels and with mdf side panels.
fans and pumps are controlled via rs232 from controller at my desk, controller has 3 solid state relays, all controlled via a pic. temp sensors sending back data via rs232 too.
old race car ecu hand controller, soon to have the lcd up and working again, reporting water temps, ambients in case and at radiator, flow rate, and internal case humidity.
