Nice start DOM

Only potential problem is once you go LN2 you can never go back
Something else that works good for insulation (I use it under the board and also to cover up any unused pcie slots is...... Frost KIng, the big 12in wide one and THAT you can get at Home Depot (about $20 a roll). only thing is it's a PITA peeling all the aluminum off, but it does do the job. Also use that for the back of cards etc..
for the most part, my setup looks pretty similar to the Dr's
Do that 980 boy
