XSReviews Prior case experience: NZXT Phantom, NZXT LEXA, APEVIA X-CRUISER, HTPC Be sure and check out all the reviews on the forums! CD/HDD bays: The GAMMA uses a very simple, easy to use screwless design for the HDDs. It's much easier to use than the Phantom's and, like the Phantom, it has rubber around the pins to reduce vibrations from the HDDs. The CD/DVD drives uses extra large thumb screws, they do a reasonably good job of holding the drive and reducing vibrations. The bays themselves are relatively sturdy but do feel more flimsy than the Phantom's and Lexa's.
Cooling: Well the GAMMA's cooling is good, it has room for six 120mm fans, however, there is a problem. High CFM fans tend to have a whine caused by the proximity to the case's mesh. This is easily fixed with grommets but is still annoying.
Cable Management: Actually the cable management is very good, there is enough room behind the mobo tray allowing the 24-pin's cable to easily fit behind the tray. There is not really much else to say about it, 1/2" of room is more than enough for most people.
Motherboard tray: The tray is very sturdy and, can fit- in a pinch- a EATX (please note that I've only tested this with EVGA's P67 FTW, which isn't really a full EATX, and attaching the 24 pin is only possible if you have thin cables, like these

PSU mounting: The PSU mounts in the bottom of the case, there are little rubber feet that reduce vibrations from the PSU. There is also a fan filter in case you mount the PSU so that it pulls air in from underneath the case.
The Looks: The case looks decent, it won't win any beauty competitions though. The front kinda reminds me of the F-117; however, the blue LED is rather boring, I replaced it with a red LED and it looks much better.
Features: The GAMMA has grommets for water cooling which is nice, perforated PCI slot covers, and plenty of HDD room (5, plus two 3.5" bays- which can't be accessed from the outside of the case).
Build Quality: The build quality is actually very good considering the price tag. The only problem I found was that the little feet for the PSU came off after only a few months. The case's feet are rubbish, they are flimsy so if you move the case around a lot be very careful. NZXT seems to have go with thinner metal on this case to save money, they only downside is the doors on each side flex a fair amount when taken off the case. Another problem with the case is the front, once you pull it off a few times it will come off way to easily. Same goes for the 5.25" drive covers.
