Removing the front panel requires a sharp tug at the bottom to release the six fasteners. All but the top-most 5¼" and 3½" drive bays are left blocked off by steel plates which can be removed by cutting or twisting them out. The plastic drive bay covers are held in place with standard tabs and are pressed out from behind. Although the second bay down is the one that has the access hole in the front, the top bay has the metal plate removed. Both the intake and exhaust fans use 3-pin connectors. The front fan power cable comes up short: it won't reach to any of my motherboard's headers. Some boards might have a connection available down in that front corner though. I ended up using a 3-to-4 pin adapter (which wasn't included) to get power to the front fan. As I mentioned before, one side of rails has quick disconnect locks to hold your drives in place. The other side does not. However, these spring tabs are all that keep the drives from sliding around. They also make getting the drives into the bays somewhat of a challenge.
The molded power cables are very nice. But this design on the auxiliary +12v is really silly. They divide the cable and allow the 4+4 connector to separate, but the wires Y, preventing you from actually pulling one of the extra cables out of the way. Only the main 20+4 ATX and auxiliary 4+4 +12v are hard-wired; all the remaining cables are modular. Ultra has used standard molex connectors for the plugs on the power supply. This is an awesome idea, as most manufacturers use some type of proprietary design. If you need to replace a cable or use one shorter or longer you can plug in just about anything you might have lying around with a molex end on it. The molded cables are very flexible and as I mentioned, an extremely adaptable design. To make the short connection from power supply to optical drive I simply used the opposite end of one of the cables where the connectors are closer together.
