    Although I do like this case and have gotten a lot of good use out of it, I wouldn't recommend it at this point. It's a 6 year old design and it's still being sold at it's original price of $80. Although it's spacious, people generally don't need 5.25" bays anymore and the hard drive cage is in the way if you want to mount a radiator in the front so needs modification.

    There's poor cabling options in the back, the whole back end of the rear panel doesn't offer a single loop for zip ties, and there's no channel so wires can start to bulge.

    My main pet peeve are the side panels, they flex easily so makes it really hard to get all the edges to catch when sliding it closed. You really have to push it against something or lay on it's side in order to get even pressure with both your elbows and forearms to slide it closed.

    i like this case. It has a nice, open design, so I have great airflow. The drive bays are easy to use, and work well. Cable management is also better than most.

    Works fine, fits fine and meets all of my expectations in a case. Not too beautiful, but at least it isn't some Dell piece of crap from some office building in 2002.

    Just a good standard metal case. It has 5.25" bay drives, comes with a fan on front and fan on back. Everything fits well. Cable management isn't the easiest with this case but definitely achievable. Love the 2 front USB 3.0 ports and the general openness of the case, allows for great airflow.

    Very, very open, and as a result definitely not a quiet case. But airflow is great, and that was his primary concern. Can take an EATX like the Gigabyte UD7 no issue (cabling just gets a bit tight). Good case.

    Great case! Easy to cable and looks great. Bought the rubber grommets for this, thought it was something that should have come with the case, but certainly not complaining for the price.

    Great case, great value, plenty of ventilation, and everything else you could ask for on a budget case. Nothing can beat it.

    Great looking case. Has all the bare necessities and the drive bays are very nice.

    Complaints: no grommets for the cable routing cut outs No way to use a 240mm radiator

    The aesthetic is rather pleasing.

    It's a great case for the money but I got it for about $50... 2 USB 3.0 ports on the front which means it's pretty much future-proofed. It's a sturdy case as well; I've had many round trips from University and home (about 100 mile round trip) and even with a couple knocks & some bumpy roads, it's managed to keep my components safe. The tool-less 3.5" hard drive bays are fantastic & easy to use, they have managed to keep my hard drive nice & secure.

    I will most likely be using this case for my next build, though I will be buying a windowed side panel. I really like this case & it's by far one of the best things about my build.

    Nice case. Got the windowed version. Can only really complain about the lack of grommets, but a 350D kit doesn't cost much anyway. The window is slightly hard to look through though, because of the fan mounts.
