Superfast PC!
Saw a PC built by a friend last week - he has bought a special cooler unit that sits under the PC and connects directly to the CPU chip, not sure what the coolant is but it goes very quickly down to -50C. He has overclocked a twin core CPU tp 5.4Ghz - goes like the proverbial off a shovel when doing intense caluclations like 3D graphics rendering in CAD, and the temp rises to -35C He has also tapped into the office aircon system to blow cool air straight into the case.
