Conclusion: Remarkably Strong

I've normally been pretty skeptical about Corsair's cases in terms of their thermal performance. Assembly has almost always been a breeze, and cable organization has seldom been an issue, but when crunch time came around they tended to linger in the middle of the pack. By definition, that's not terrible but it's not great either. On the more expensive cases it becomes a problem, especially if they're competing with air cooling juggernauts like the SilverStone FT02.

Yet when we're talking about a case that's under $100, trade-offs become a lot easier to swallow. That's part of what I like so much about the Carbide 300R. While acoustics are somewhat weak, the feature set and performance make them much easier to live with. Laterally oriented drive sleds, solid cable routing, toolless drive installation, USB 3.0 support...there's a lot to like about the internal design.

The 300R doesn't have any means of really dampening sound and so its acoustics can frankly be pretty lousy (particularly with a high-end overclocked system), but for once Corsair has done a bang up job with thermal performance, offering a case that's frequently very competitive where it counts. It still can't beat the Antec Eleven Hundred, but Antec's case also costs at least $20 more and isn't as easy to service as the 300R is. If you build the 300R smart, I believe you can definitely improve the acoustic performance.

Ultimately if you're in the sub-$100 market for a case, I think the Corsair Carbide 300R is going to be pretty close to ideal for end users looking to maximize performance against budget. The only major competitor in my mind is going to be Bitfenix's Outlaw, which sells for $30 less and pretty much steals the show in that market. Yet the 300R is more feature rich, easier to assemble, and allows for a 240mm top-mounted radiator if you're looking to spend up on cooling. It's not a homerun, but it's pretty close. At $79 it's a solid deal; if you find it for any cheaper than that, grab it.

    Got one of these a few days ago. It's worth what you're paying for it, but it's not worth more.

    The USB 3.0 connectors do not look rugged, it will be painful to see them break. The side panels are unbraced sheet metal just like any cheaper case, they may need sound deadening sheets to quiet and strengthen them. In every other way though, it's a nice case.

    Your review is fairly late coming, but you did it justice I think. I've owned this case since it came out 5 months ago. Only cons I can give it are 1. they should have gone ahead and punched out the water cooling holes on the back. The steel back there is very thin and its easy to damage the case punching the holes out...and 2. just a few more millimeters of cable routing space behind the motherboard would have done a world of good. For the price, this case gives you a lot of options and the ability to put 6 x 140mm fans in it. You can buy the cable routing hole grommets from their site if you want that option. The Obsidian grommets fit it. Having that large open cavity below the 5.25" bays requires some creative cable routing if you want a clean look, but it can be done. The USB 3.0 cable is black thankfully, not blue like so many other case makers feel the need to do. I immediately switched out the included Corsair fans, so I can't comment as to their performance. The expansion ports aren't tool-less, but at least they give you thumb screws for them. I was coming from a Lian-Li PC-P50 and I actually like this 300R better. It has a great use of space for it's dimensions.

    I know you say the form factor supports mini-ITX, but Corsair won't guarantee me it when I contacted them. I have an ASUS P8Z77-I DELUXE mini ITX motherboard and want to be sure it fits the Corsair Carbide 300R. If not I was thinking about using the Fractal Design Core 3000.

    Did the hyper 212 evo fit with the case closed?
