Summary: Do not buy. The case only has 1 fan and mine was missing 2 side rails for mounting a second optical drive. Antec's customer service is very unprofessional. It did not have a hole for one of the motherboard mounting screws. It attracts a lot of fingerprints. Not a lot of room for cable management. Power button is flimsy. There is some space on the sides of the optical drive. And the case is heavy.
Summary: If you don't like noise, this is the case for you. The side panels have a second plastic noise-absorbing layer on inside-facing surfaces. The one 120mm fan uses a rubber anti-vibration mount, and moves more than enough air despite being extremely quiet (19dB according to the spec). For further silencing, it has a two-speed selector to reduce it's RPM.
Summary: Quiet, classy, and attracts fingerprints like a magnet. I've loved having filtration though, which is useful living in a desert. Very easy to set up a front to back airflow too, without lots of extra vents to complicate things.
Summary: This is a wonderful and functional case. I became obsessed with quiet computing, and this one seemed to fit the bill. This is a bit expensive, but not too bad. The screws for taking the side off are built into the panel! How genius is this! This is for the 'main' panel that you take off (left side). The other side has regular screws that you'd need to undo.
Summary: This case does what it says and is good for a midsize quiet computer build. However it is tough to work on and not flawless. There is a vent on top for the power supply that is not silenced in any way, so using any power supply with a fan that spins constantly will not do. Likewise space on the inside is very tight and some of the vital areas are difficult to access.
Summary: Then use this case (with its now-less-common power supply location) and the KingWin Stryker 500-Watt ATX 500 Fanless Power Supply STR-500 (or another one in the series). Want it to be super-silent? Use only SSDs. I've been using this since February with no issues and no noise. I have my computer in a home studio, so quiet was key to me and this delivers in spades. Plenty of power for my Ivy Bridge with 4 hdd/ssds, etc. I don't have a power hungry video card.
