well I've started construction, I got a deal on some 7/16 grade (it's acc just over 3/8" thick) clear and i ordered a sheet of 1/4" grade (.236 nom) of grey it's comming allong a bit slowly ATM but i should have some photos of it -without the top and front doors, and drive bays in a few hrs to a day.
thanx again for the help and advise.
dorian:
In working with my last performance pc i had no problem keeping the cpu and video cards cool but the NB, SB, and the ram tended to overheat... so for this setup full innersion... the real coolong system in this is a two stage setup, first the oil is pumped thru a 3 fan cooled radiator then it goes into a TEC cooler before returning to the tank.
the radiator i'm intending on using is rated for well more than the pc's wattage (ie the btu's generated, and yes wattage isn't a supper accurate method of determining btu's but thats how the pc equipment is rated), and should take the oil down real close to ambiant ait temp. the tec cooler is being designed to provide about a 15 deg c drop, with power to spare for temp regulation.
the mobo will sit with the connections at the top of the tank above the "water line" but still closed inside the case, i'll prolly build a connections panel (with short jumpers to the mobo) into the upper back panel.
as far as dangers... mineral oil dosn't conduct electricity and dosn't soften/eat at any of the componets used in the computer at all. even with 120vac in the tank you can place your hand in the tank safley. years ago mineral oil was used as a liquid insulator for some types of transformers.
mineral oil has a flash point of 135C (275F) and a autoignition point of 260C (500F)
it has a Flammability Rating of 1 - Slight so there is really no risk of it deciding to light up.
also there are now 2 immersion type pc's avail on the consumer market (they are just both very limited in the H/W choices avail for them and the cost is very excessive- $3000 to $4500) , but alas the cases are not for sale you'll proll see some avail in a year or two though.
