Installation:
For installation you will want to make sure you have a large flat surface to work on so you can lay the Matrix case on it's side. As seen in my pictures, the sides of this case don't quite come off like a normal side panel would. Instead, the side comes off but it also brings half of the bottom plastic portion of the case as well. For that reason, you can not disassemble the case while it's standing up or else you won't be able to properly pull the side off. When I had the case laying down, it took a bit of a push but the side did slide off fairly well. Inside, the case was neatly layed out with a plastic barrier going down the middle to better direct airflow and eliminate back draft from the CPU fan. Video card clearance won't be much to worry about because enough internal space is left to support four full-size cards.

(Left side piece on the bottom and the back cable cover door is on top)

When you're installing a system from scratch you also need to remove the front bezel to allow proper access to all of the drive bays; this was fairly easily done by popping out a few plastic clips. If InWin really wanted to impress me in the future they would take a case like this and add a few tool-less installation features on the inside since that would be very inexpensive to do.

Overall, I had no bad notes to point out during installation other than the fact I wish they'd have the side panels come off like any other case instead of removing half the bottom with them.

Testing:
Since there isn't a whole lot to test in a computer case I usually use this time to evaluate the overall stock cooling noise level. In order to do this effectively without introducing any further noise, I use a power supply tester and disconnect every internal component except for the included power supply and the one cooling fan. The Matrix left me quite surprised at how astonishingly quiet the included cooling system actually is! The power supply itself is next to dead silent (only a hair louder with components connected) and the included drive bay cooling fan is still fairly quiet although it did stand out as being one of the louder cooling components. If you're not running large or hot hard drives then it wouldn't be a bad idea to wire this fan for half power to quiet it down while still allowing it to perform some light cooling.
