I have a thermaltake Armor MX case with a Big Water 760is. I just ordered a GA-EP45-EXTREME and I want to hook up another rad and fan for the northbridge pipe system. On top of this I would like to have a temp monitor and flow indicator that will fit in that 3.5 in slot at the right abover the BW. Got any suggestions? I also got just bought a 600 Watt ThermalTake PS, how will I know if I bought enough?

Thanks
Bob
