The frame is from Rich at
http://spotswoodcomputercases.com/wp/?page_id=875. He can modify however you want. I asked him to add that fan mount. He sends them n pieces and you just assemble. They are aluminum channel.
I've not run the rig with the fan tray off, but in a cool basement in the northeast USA, the card run around 70c. With afterburner setting that card fans at 55% constant.
