So little copper on the thing you will have get yourself a Tsunami water pump to get it cool better than stock.

The claim of 20C is pathetic. Thermalright GTX will cool way better @ 1/3rd the price and air only, except that TR doesn't yet have a compatible 4890 cooler.

lol!, i can already see the device.

"install the [clicky market name here] and take some load off your PSU!"

Water in one hole steam out the other?

Perhaps a steam turbine can be added to the pressure side of the system to help return some of the energy that this thing is going to use.

Also as posted above, this may be a single slot solution but have fun with plugging anything into the slot next to it!

that picture sure doesn't show a single slot solution
