Man that is just awesome. Please post more information.

So far it's 4x5870s, MSI 890FXA-GD70 mobo, Antec DF-85? That all makes sense. But how exactly do you keep it cool?

What are your cores/memory? MH/s? Temps?

It looks like you added a 120m side fan, that case must have amazing cooling to just need 1 more fan to run 4 of those cards.

They look amazing, thanks for posting!
