I was trying to get an idea of you load temps with the side panel off..my guess is you'll be in the 50-55 degree range under load. I just ordered two 70mm fans for the back of the case and I'm going to cut two 2.5 inch holes where my three 40mm fans are currently. I think that will keep that part of the case vented appropriately. I might have to file the fan casing down just a little to make them fit though, but it'll be worth it.
