I wanted to make a couple of external HDD bays for this case. The idea is that you should be able to change drives just by inserting a new one in a slot on the side of the case, in a modular fashion. I'm making the "slots" from orange, and some smoked acrylic, then cementing them together.
After making the external cages, they needed to be connected to the system in some way. I got two AC Ryan IDE to USB adapters to use for this purpose - since USB would allow me to plug and unplug them at will. The adapters themselves are way to large to fit underneath the bay, so extending the connector seemed to be the right thing to do. I sacrificed a flatcable, and split up all the conductors. This is a tricky procedure that requires a very fine, very sharp knife.
Putting the drives together required some assembly, some soldering, and some careful test-fitting. They were then ready to be integrated into the case.
