Remember the sweet joy of removable motherboard trays? These seem to have gone out of fashion, but are making strong come back in many aluminum cases today. The motherboard tray on the Coolermaster WaveMaster is held in place with a few thumbscrews, and can be removed in a few moments for easy installation of components.

Getting the motherboard tray out of the computer may have been a snap, but sliding it back in proved to be somewhat challenging. The rail the motherboard tray slides along is aluminum, and the tray is aluminum.... the two surfaces have a tendency to bind together, forcing the user to bang in the tray to get it to seat fully. Some low friction tape on the rail would help fix this I'd imagine.

Another potential problem I can see popping up has to do with 5 1/4" devices interfering with the WaveMaster door closing fully. For example, devices such as the Soundblaster Live Drive have features that stand out slightly above the case bezel, and given the way the door of the WaveMaster comes to within 1/4" of the bezel surface, anything taller than that will prevent it from closing all the way.

Unbelievably, Coolermaster's own Musketeer drive bay caused some problems with the door closing. One of the switches was just a little too tall! Given a small round file, and a few minutes, this could be easily fixed by filing back the screw holes the 5-1/4" drive attaches to, a few millimeters.

Basically though, the front bezel wave design is nice, but manages to cause a few headaches if you are using anything other than a flush-to-bezel CD-ROM with this chassis.
