First, the S-915 looks the part. Up front, the brushed aluminum locking bezel neatly hides your power button, reset button, indicators, drive bays, and USB port. The locking mechanism is strong enough to withstand a decent pull and all the locking components are made of steel. The top and bottom of the door are vented and filtered to allow airflow to travel through the front of the case while reducing dust. If a locking front door doesn’t do it for you, the hinges are held in place by four Phillips head screws and can be easily removed.
The top of the case features the single 80mm exhaust fan.
The side panels are held in place by industrial spring action thumbscrews and are easily removed. For people like me, the people who always lose screws, the thumbscrews stay attached to the side panels. The left side panel has a filtered air intake and the right side panel is featureless. The intake on the side panel is positioned so that your PSU can draw fresh cool air.
Around back you have two expansion slots as well as the PSU and motherboard cutouts.
If you have noticed the modular design that some case makers have incorporated lately, you can attribute that primarily to the industrial case market. It is no different with this case. The motherboard sits on a removable tray, the 5.25″ rack is removable, and there isn’t one rivet to be found. Everything is held in place with screws, even the brushed aluminum garnish on the front bezel.
