As noted earlier, the overall dimensions of this case are a good bit larger than your normal run of the mill enclosure. But just think about how much room this has created on the inside. Not only does it give you more space to work in, it also has allowed for Thermaltake to add more features. So let's see what we have waiting for us in here, shall we?
Starting at the top we have the optical drive bays. While there isn't that much of a surprise in this area, there is a new rail system that Thermaltake uses that does away with screws. There are plastic studs on the side of the rails that just poke into the screw holes of the device. Once you place then there, they simply slide into the appropriate drive bay and then they lock into place. Here is a picture of one of the devices with the rail clip seated.
Since there are not any large gaps or holes in the shell of the drive bay, the rail has no chance of slipping so the drive stays firmly in place. I have learned to enjoy rail systems for cases, but this is a new method that I haven't seen before. It is simple and effective and also makes for a tool-free installation of your drives.
There are two 3.5" externally accessible drive bays to work with in the Xaser III so there shouldn't be any real problems for a vast majority of the users. I was happy to see that they didn't just do away with this part of the case design. Some manufacturers have begun omitting these bays, but I still believe that the best way to Flash a BIOS is to do so from a bootable floppy disk. It also comes in handy for diagnostics, so thank you Thermaltake for leaving us the ability to use our floppy disk drives.
Of note is the fact that this is one of the few areas in this case which requires you to use screws. There is no rail system for the FDD bays, so you're stuck with doing it the old fashioned way. Oh well.
