Summary: Even when the package arrived I had no concerns with size. I was certain that any part I wanted to install in this case would fit. Much to my surprise I had trouble with my GPU and Water Cooling fitting. I had to move the piece for the middle wind tunnel so the GPU could fit (GTX 770 4 gb, classfied).
Good but not quite perfect. Documentation does not match current product.

Summary: I bought this not for a gaming machine but to house a NAS system, with hard drives mounted in hot-swap drive cages (two iStarUSA BPU-350SATA-BPL cages to start with, and room for another later -- each holding five 3.5" drives in three 5.25" drive bays and with its own cooling fan). My old case (brand unknown) used mounting rails for the drives, so it was very easy to install the drive cages.
Summary: I upgraded from the 900-2 to this 1200-V3 for my i7 4770K build. Although I can get away with a mid-tower, going with the full-tower is the only way for me henceforth. There is LOTS more breathing room. All components run much cooler with less fan speed than required in my 900-2. With the extra space I don't have to move or unplug components to access the hard drive headers (or any headers for that matter). Access for modifying and cleaning is very convenient.
Summary: This case is heavy to begin with. It has in total 6 fans and they all look great. Unlike the old Antec I had with similar colours, this one does not illuminate the room (which is a good thing). Taking this apart to put in 3.5" HDDs is not what I consider straightforward. The manual does not come with it so you need to get that on-line. Once everything is in, it works great. I just do not want to think about taking it apart again (which is kind of a huge drawback).
Summary: Tons of room for everything. Six fans come stock with 2 optional locations for 120mm fans. The front panel is all USB 3.0, just make sure your motherboard can handle that. Overall I love the case and many people who see it love the blue LED and the clear side panel. I would buy this again. The only small frustration is the lack of really good instructions.
Summary: This is the case that will satisfy tech savvy buyers for all your upgrade needs including that extra long length video card that you hesitated of buying because you were afraid if it might not fit in your case. Overall an excellent choice for custom PC builders.
Pros: Very roomy space for great customize-ability. Excellent case ventilation. User adjustable fan speed and tri-cool led fans included. Redesigned with rubber holes and better cable management. Excellent build quality and durability. Quiet Fans
Summary: Received the case today and the installation was easy. The case could do better on cable management and drive bay installation if you care about that. So if you are not good at cable management then the see-thru panel is useless. The case comes with six fans and two optional fans if needed so if you plan to use them all make sure your mobo has enough connectors to power them. I like my new case.
