PC Case Made Completely of Fans

drgroove writes "I work in a computer store building PCs all day. With every new case there are one or two 8cm case fans included. Most of the systems we build do not need any more cooling than is supplied by the CPU fan as most of our customers generally don't go in for all this 'overclocking malarky.' Looking around the stock room I discovered two large boxes of unused 8cm case fans. Surfing through case mod sites, the most popular mod you see (besides Lexan windows) is some form of whizzy cooling device, be it fan or waterblock. People go to great lengths to keep their PCs cool. Now... putting these two things together..."

Airflow is backwards:

He claims "Looking from the front of the case, air flows in through the left side and out the right side. The front an back blow air into the case and air flows from the top of the case down and out the bottom... theoretically anyway."

Ideally, the top/bottom flow direction should be from bottom to top, since the coldest air is on the floor of your room (heat rises). Most datacenter-class stuff goes bottom to top as well, but that's just because that's where the A/C is, underneath the servers in the raised flooring.

And having two major airflows intersecting in the case (left->right vs top->bottom) seems inefficient as well.

Personally, I would have set it up with the bottom, front, and back as intakes, and the top and both sides as outflows. Only issue there is the usual power-supply placement puts it outflowing on the back, but I guess in such a custom case you could move the power supply so that the "rear" of it is blowing out one of the sides or the top.
