External and internal
Removing the right-hand panel from the case which, incidentally, is completely tool-less shows us the uninteresting side.
Notice how it's braced up the middle for extra rigidity and strength. You can also see that the removable tray is internally braced, too. I had no problem in subjecting my full 70kg frame on the case by standing on it, repeatedly. You can see all the motherboard connections bundled neatly on the correct side.
Turning to the back:
Fan #2 of 4 sits just below the PSU slot (not supplied). Geared towards extraction of the heat produced by the twin evils of the CPU and graphics card, it's handily placed. A quick note here,Ā the PSU installs from the inside.
This picture is just a close-up of the back, with a particular focus on the groove that helps you lift out the motherboard tray with ease. There's no real need for Cooler Master to do this, but it does show attention to detail. Simply unscrew the thumbscrews and pull out the tray by inserting your fingers into the groove. Out comes the tray.
Cooler Master tout the 110B-SX1 as an all-aluminium case. That's clearly not wholly accurate, as the tray is steel. You can see it's further reinforced on both sides. The extraction fan sits in its usual location.
As the case is deeper than most midi-sized offerings at 535mm, the tray is large enough to support server-based boards.
A dual Xeon rig in its making. The 110B-SX1 comfortably holds the rather wide enhanced motherboard.
Removal of the tray gives you this pretty picture. Fans #3 and 4 are placed at the bottom of the case. With hot hard drives being able to populate a number of bays, having extra cooling is a thoughtful extra. Their molex power connectors are bundled neatly close by. The darker background you see to the fans is Cooler Master's pre-supplied dust filters. There's nothing worse than a dusty case. You can just about see the extraction fan on the right-hand-side. It's at the top of the case, as shown in the first picture. A decent size, well though out layout, and a number of fans for extra cooling make it an attractive proposition, so far.
