OK, well I'm going to ask the builder to put 2 holes for 80mm fans on the top of the back panel and 2 holes for 2 3/8" diameter grommets (for wires) on the bottom of the back panel.
I think, circulation-wise, for removal of hotter air, it would make more sense to have a fan at the bottom and one at the top of the panel, but I think this wouldn't look very good...
Anyone think this is a big mistake? I would think two 80mm computer fans would be able to provide enough circulation that placement isnt as large of a factor...
