The sides on the PC-A77 are entirely plain, consisting solely of vertically brushed aluminum panels. While some people think of this as boring, others see this as sleek and stylish. Still, others find these panels attractive because they are extremely modifiable. Indeed, while they are made of thin sheets of aluminum, which are great for cutting, they are also extremely sturdy. Each side panel is held onto the case with three thumbscrews in the back of the case.
The bottom of the case is similarly as uneventful. One fantastic feature here, though, are the case-feet, which are outfitted with soft rubber rings on the bottom, reducing the case's vibration against the desk or floor on which it is sitting. Though this seems like a minor detail, it does wonders for the acoustic value of the case.
Moving to the rear of the case, we find the busiest part of the exterior. There are a lot of thumbscrews back there, but each has their own purpose. At the center of the top, there is a large, sturdy fan grill attached with four thumbscrews. Behind that grill is an exhaust fan, which pulls air past a 3-bay hard-drive cage. If you don't need the extra hard-drive space, or prefer to have your cage elsewhere, this can be replaced with the extra PSU bracket we mentioned earlier.
Just below this cage are the water cooling brackets, which are made of cheap plastic. It would have been nice to see rubber here. Below that is the rear exhaust fan, which has a true grill, not a stamped honey-comb or stripes, which means that not only is it not restrictive, but it also is easily replaced with a custom grill. On the left, we find the IO panel. A generic IO plate is not included, but those are generally outdated and a waste.
Moving to the bottom of the case, we see the vented expansion slot guards. Here we find the first PSU bracket, which, again, can be moved to the top if you would like to swap things around. On the right and left, you can see the thumbscrews used to keep the side panels in place, as well as extra screws on the left. These extra screws are used to keep the removable motherboard tray in place.
This about wraps it up for the exterior of the case, so continue as we move on to the interior.
