[lug] combatting hard drive heat

[Mr Viggy]

You might try to find a peltier element.  I don't know how handy you are 
with electronics, but if you get get a peltier element, you might be 
able to wire it into your power supply.

If you don't know, a peltier element is basically an wlmost paper thin 
device that will get really cold when electricity is passed through it. 
    Those car refrig's ususally have peltier elements in them.

Unfortunately, I really don't know where you might find one the right 
size (sorry!).
