I love this case: I used it a few months ago to build my first windows PC in years, and it definitely holds up. It's very roomy, solidly built and most important of all, quiet. It is very easy to install a proprietary Antec power supply.
Unfortunately, there are a few shall we say mishaps in (at least) this revision of the case that will affect your ability to build a system with it (but probably won't affect the system once it's built):
One, to hook up the USB3 plug in front, you pull a cable all the way through the case, out through a hole in the back, and plug it into a regular USB3 port on the mainboard in the rear. I am guessing there was no reliable spec for mainboard USB3 headers when the case was made, but huh, this looks seriously ugly. Especially as the cable is too short to usefully route next to the main board tray.
Two, if you have a very long video card, you won't be able to use the top 2.5" HDD cage. I had to get a set of 2.5->3.5" conversion brackets in order to mount this system's SSD in the lower drive cage. That was a bit disappointing, but I was waiting for some other components at the time anyway, so no time lost. If you are considering putting an SSD and a long video card into this case though, better get some brackets as well.
Three, the cable-routing partition behind the mainboard tray is very very narrow. The Antec CP-850 850 Watt CPX Power Supply Unit's cables do fit there, but when a few of them are in there, it's hard and fiddly to close the case.
Like I said above, these problems affected me only when building the system. Now that it's fully assembled, I'm happy as can be. My box is stable, well-cooled and very very quiet. I'm keeping it in my living room and can take naps next to it: That's something I have never been able to do with any other machine I've owned. (And one of them was a Mac Mini!)
