Mike Harrison got tired of having to grope the back of his PC plugging and unplugging things all the time, so he made a backwards PC case mod!
I'm sure there must be plenty of tecchie types out there like me, who are forever plugging things in and out of their PCs and don't want to be groping around the back all the time. For a long time, I've been frustrated by how essentially identical most PC cases there are, and that nobody to my knowledge has ever made a case which has all the drives, IO connectors and PCI slots on the same side. (There may be a few industrial cases, but these are usually very expensive.)
As I like to have things the way I want, I've had to resort to metal-bashing to produce a case thet meets my needs.
