A tower indeed

Pros: Very sturdy

Cons: Dust filter does not work very well; weird vent opening on top of the case; little space for arranging cables in back side panel

Other Thoughts: Case is pretty big and quite dependable. Only cons are;

The vent opening at the top (I suppose to let out heat) of the case, which makes your system vulnerable to any spills or dust. I currently am keeping a film over it, which doesn't look quite as nice.

The side panel for running all of your wires through provides little width and I had trouble getting cable to and fro in an organized fashion. One of my sata cables has to connect at a 90 degree angle (not sure if thats good over long periods D:). It is a first build, though, so maybe just lack of experience.

Quite a bit of dust still gets into the case.. Which seems to differ with reviews on other cases.

All in all a good tower otherwise.

Got in 2012, still a great case. Build #3

Pros: Lots of space, lots of 140mm fan ports.

Cons: Not much to dislike. It's a little plain, when I got it it didn't have a window option. It's a bit difficult to clean the front fan ports.

Other Thoughts: If you get the non-windowed option. Get a magnetic fan screen also!

USB 3.0 Problems

Pros: - The Case is a good upgrade for any ATX or Micro ATX Mother board that needs more room, this case has plenty of it
- The Case has good air flow, has 2 large fans already installed not to sure the actual dimensions but they are bigger than 120mm, other than the fan the case it vary open with mostly being large mash patterns to create holes for air flow.
- the price was fair until you see on of the cons about the USB 3.0 in the front panel I/O.

Cons: When i received this case i liked it very much, started hooking up my mother board and my new cooler master hyper evo heat sink, got everything hooked up all cables attached to their appropriate headers, and everything looked good, turned on my computer, the USB 3.0 port on the front panel I/O was not working, instead o port was just making my turtle beach receiver flicker, the other was not working at all, i contacted corsair they replaced the part for free pretty fast, i just got it today and hooked it up only to find the same problem, i know it is not my USB 3.0 Header as i have tested it with a different cable and it worked, the is defective, and the sent me another defective part.

Other Thoughts: While the case is good, i would recommend buying a separate USB 3.0 Cable, and just replace the part your self because you are only going to receive the same defective part you had in the first place from corsair and waste your time installing, that said the case is not bad and neither is corsair e.g. ( i have a corsair power supply and ram with no problems ), i just wish that they would properly check the parts that they are giving to their customers so that situations like these don't happen, so all in all the case is good, front panel USB 3.0 ports are bad.

Great, sleek design, however...

Pros: -Very nice cable management.
-Roomy without being obtrusively large on your desk. Really the perfect size.
-Very classy design (doesn't scream at you, but definitely has an edge to it if you add the right components)
-Easy access to the insides. The side panel comes off and back on quickly and easily.
-Large window for viewing all of you expensive components and tricked out LED's. However......

Cons: Why, oh why does corsair not offer a window on this computer without the holes for the fans??? I knew what I was buying, but over time this has annoyed me to no end. There are entire threads online on how to diy yourself a new window, because most people do not want the holes. Corsair, could you please offer a window without the holes on your website? I will gladly pay for it, as will many others.

Other Thoughts: Besides my obvious gripe, I love this case! I would definitely recommend it, but not if you want a nice view into your computer, because that it will not do. Would I buy it again? No, I would not. But that is my personal preference. I would opt for something that has a clear view into the insides. Everything else about the case is fantastic though, it is a great design.

Carbide 300R

Pros: roomier than expected for a mid-tower
WELL laid out
the hard drive trays all have screw holes for SSD's
solid construction
cutout in drive cages for bigger video cards
lots of space for fans or liquid cooling systems(though a custom loop might be tough to squeeze in)
corsair provided WAY more stuff than needed, extra screws and zip ties etc which they didnt have to do
for a "budget" case this thing is unbelievably sweet

Cons: standard hard drives dont fit perfectly in drive bays, the trays get..."stuck" for lack of a better word but it was do-able

Other Thoughts: truly this thing is amazing, im not used to mid-tower chassis's anymore so that takes some getting used to but thats not corsair's fault
i have not used a corsair case before but i will be back next time i need a case

Solid case after 2 years

Pros: The airflow in this case is amazing. You can mount 5 120-140 fans and 2 140 fans for intake at the front. There is a separate intake for the power supply with its own filter which is great where I am is really dusty. Being able to remove and use the left side to hide cables makes cable management very easy.

Cons: I mounted a water cooler with dual fans to my CPU and case and because of the size the water cooler presses against the motherboard and made it very difficult to mount my Ram to my board. This is where I subtracted the 1 egg.

Mounting the side of the case is often a choir as you will have trouble aligning up the top and bottom so they fit clean.

Other Thoughts: Clean the filters often as this can easily mess up your cooling.
