Case fan mounting

The case fan will be mounted under the handle on the top of the Detectron case. With the plan to add hinges to the Detectron lid, space was vary scarce, and the case fan needed to be situated all the way to the backside of the case. To support both hinges and case fan, a very satisfactory wooden backpiece was constructed.

However, this turned out not to work at all for mounting the hinges, as the revolving axis needed to be further in than what this construction allowed. Hinges are terrible things, that will be painstakingly described later. There was nothing else to do than to scrap this nice one, and make a new version of the backpiece. The fan will be mounted directly on the grill using four longer bolts, and eventually using nuts instead of a rubber band.
