Inside the BitFenix Merc Alpha Mid Tower Case
With both side panels removed, we can now see where the paperwork and hardware are stashed. In the bag tied to the hard drive rack, the manual is shipped with a bag of hardware together so nothing gets lost or gets loose during shipping. The wiring is tied up as well to keep those from doing the same.
The three 5.25" bays offer plenty of mounting holes, but I am afraid there aren't any tool-less clips to help you out. Instead BitFenix uses all thumbscrews for these and the hard drive rack.
All seven of the bays for the 3.5" drives are labeled so you know exactly where to put the screws. The top two bays here can be used for a floppy drive, but of course only the top one lines up with the removable cover in the bezel.
For an ATX motherboard installation you don't use risers but rather bumped up bits of the motherboard tray with tapped holes in them. The center riser is actually a pin and holds the motherboard in place while you add screws to all the other holes.
Inside the rear of the chassis you get the only included fan in the Merc cases, this 120mm fan with a 3-pin connector on it. Keep in mind you will either need a Molex adapter or be sure your board has a free header.
Just like in the Outlaw, the Merc has no room behind the motherboard tray either. These cases use a system of holes and the offsets of the drive bays to be used for wire routing or extra cable storage.
The amount of holes, size of them and small holes drilled in the tray differ from the Outlaw, but as you can see, they give plenty of options for places to route through and the depth of area next the hard drive rack will accept a lot of wiring before things get out of hand.
Removing the front bezel takes a fair bit of effort as the pins that lock the plastic to the steel are tight and don't want to let go without a manly pull of the plastic. The wiring of the I/O is connected to the bezel and runs through the wide rounded holes at the very top of the steel frame. In front of the hard drive bays, this case will accept a pair of 120mm fans there.
All four of these wires are two foot long and will reach from the top of the case to the bottom and then back up to the motherboard with a bit of slack still in the wiring. Both USB 2.0 connections, the HD Audio connection and the small motherboard connections are all covered in black to keep things clean once the build is finished.
