They are well known to overheat very quickly. I think there is a youtube vid of one running.

one other problem would be dust ..as soon as it becomes saturated then you have the problem of conductivity and everything go's pop .. or you do when sticking your hand in it ...
so you would need a sealed system ..

Yeah - that was one of the issues I'd hoped to discuss with someone who has done it before. I'm thinking maybe just a sheet of wood across the top with a few small holes for the extension leads to drop into the oil, the squirt some resin round the hole/cable edges. Not sure what the experience of others over the long term has been.
try using the back of an old case with board attached that way top of board and connecters stay out then 2 pieces alu running down each side seal with a thick wide tape but your gonna need a pump and rad ..
but you can fix that to one of the pieces of alu ..pump will give oil movment ..throw in a couple of led's and plastic fish![]()

I think some of you are over egging the heat issue, will depend on the parts used but overall that amount of oil has a huge heat capacitance, remember that cpu's will happily run at 60c and gpu's at 85c, temperature issues start to come in when overclocking.
Yes the oil will heat up but unless you're running 100% load 24/7 there will be lots of down time when the oil can radiate off the excess heat and your ambient temperatures may be slightly higher than air cooled.
If the ambient oil temperature becomes an issue a submerged pump connected to a large external passive radiator could well sort out any issues.
EDIT: if you look at that kit website the smallest they do is 6 gallons US, that's just under 23 litres, your average water cooling loop has under 1 litre of fluid in it, granted water has a higher heat capacity per mass (4.186 joules per gram per degree C for water vs 1.67 joules per gram raised 1 degree C for mineral oil) but you still have a lot more heat capacity because of the volume used
Dust and conductivity is a pretty much a non-issue, this is not water where you've got lose hydrogen ions kicking about because of impurities, the worst issue you'd get would be from large amounts of dust thickening or gumming up the oil and/or heatsinks.
If the top of the tank is covered then you get very very little dust penetration anyway, remember that normal cases build up so much because they are constantly sucking in air.
Oil used, you can use cooking oil or motor oil but both have issues, most cooking oil oxidises over time thicking and discolouring, and both are normally thicker and more viscous so will not move as freely.
The stuff generally used is mineral oil which is a very light and stable oil, it's generally used for more delicate high speed machinery (sewing machines) laser copier/printer fusers and as a laxative for large animals (horses, cattle and pigs) you can get it from veterinary suppliers but not in the volumes you generally need.

Although all told a normal passive system might be a better option for a silent pc than mucking about with oil baths
eg a cooler like this http://www.quietpc.com/nof-icepipe
with a passive graphics card http://www.quietpc.com/sap-hd7750-ult , fanless psu and ssd's would be the simpler option
