I'm glad to find that this thread exists, because I have some problems and a lot to say about my 300R. I've had it for just over one year and I have had issues (some solved, others not so much).
I'll share a solved problem first - nothing fancy, but it was a quirk with this case that I had to take care of:
My headphones kept popping out of the front audio jack. This was a small, but very annoying issue. They'd pop out halfway so that only one side was getting signal. I was able to narrow this down to the jack on the front panel not being flush (it is sunk in a bit, set behind behind rather thick plastic). I was able to solve this problem with an electric drill and a countersink attachment. I used the shallowest countersink I could find and drilled straight into the hole (with the front of the case taken off so that the jack wouldn't be damaged, obviously). This removed enough material and allowed the headphone jack to work normally.
Next, I have a recurring intermittent problem that has been very difficult to diagnose:
For the entire time I've had the case, there has been an issue where plugging any device into the front panel caused an immediate crash. This did not happen with any consistency, but at first I attributed it to bad audio drivers because it was always happening when I tried to plug in my headphones. But then it also happened with USB and anything else, so it was a mystery to me. I assumed some sort of defect in the front panel but was too lazy to do anything about it especially since I'm not good with that sort of thing and had no idea if I was right. I only determined the actual cause recently.
After the problem had been relatively infrequent for a while, I had all but forgotten about it when it started happening frequently again this winter. Gradually I realized that this was an important observation, but I had no idea what variable had changed. The answer came on me suddenly when I was talking about how I don't use a humidifier, because of my allergies. Besides being bad for dust mites, dryness also promotes static electricity, which turns out to be the culprit! I have since been in the habit of touching connectors to a metal surface on the case before sticking them into their ports. I have had no further problems, and I'm not worried about the damage those surges may have been doing since I just finished a new build. I would still like to ditch this procedure, so my hope is that someone can lend insight about whether there could be some sort of bad ground in the front panel.
- The doors on this case are a huge pain. Coming from Antec for my last build, where it was just basically a single pivot, this method is more secure but at times extremely frustrating. I've gotten much better at it over time, but in the beginning it's very difficult to get all of the slots in. Every time I thought I had it, one was popped out and I had to start over. These days it takes me one attempt, two if I'm not paying attention and mess it up - still, it shouldn't be that hard.
- I never thought I'd say this, but there are too many fan slots and too many vents on this case. I have 140mm fans, I have tried running all of them in a logical way but it's just too many. At best, you end up with 4 x 140mm intake, 2 x 140mm & 1 x 120mm exhaust. There isn't really any other way that makes sense, and it leaves such a huge difference in intake and exhaust that the case actually makes a resonant "wub" sound from pressure building up and escaping. It's bad. I ended up disconnecting the side intakes and the front-top exhaust (which makes very little sense to begin with). One of the things I liked when I bought the case was the potential for great airflow, but it only allows for really bizarre setups. I chose instead to just plug up some holes and use it like a normal case.
- I think it's pretty silly that this case comes with a dust screen on the front, and one under the PSU, but then has a giant gaping hole in the top. Even with 140mm exhaust fans mounted there, it collects dust. The mesh is larger than the fan slots, so the airflow will never be enough to stop that from happening. I bought some magnetic dust screens for the side intakes, but there is still the issue of the top mesh. I'm hoping to mod the case or just find/make something that will fit over that perfectly, with just some holes for the fans. Just something to block airflow through that mesh, without looking awful. Suggestions would be appreciated.
- I love all of the holes for cable management, it's fairly easy to keep this case clean and organized.
- The hard drive racks are pretty cool, but ultimately pointless. I'm not hot-swapping drives all the time, few desktop users are. It's nice to not have to use hardware, and it's nice that the orientation of the drives frees up some space, but it also creates problems. Having sideways drives means that SATA cables get all bunched up in the side of the case, so you basically need to have right-angle connectors (but then they're blocking each other, so it's just a headache).
- The dust screen on the front of the case is hard to clean. You either need to clean it from the front with a vacuum (doesn't work well), or bend the tabs that hold the metal grate around it. It's obvious that it's meant to be removable, but those tabs are annoying and they will eventually break from the constant bending back and forth. Again, this is an area where my cheap old Antec case beat Corsair.
I like this case, but the only reason I bought it originally was because it's so large for a mid tower. I had just purchased a new AMD video card, and shortly thereafter discovered that it's massiveness would not be accommodated by just any case. Still, didn't want to make the jump to full. I'd say I've been happy with it overall, there are just a few mild quirks that bother me.
Edits for spelling etc. (sorry for the long post)
