4 out of 5 eggsStylish an inexpensive

Pros: +Sleek styling
+lots of room for upgrades
+the trays for smaller SSD drives are very nice
+Cable management is.... okay...

Cons: I purchased this case with a thermaltake 2.0 extreme cooler in mind for my cooling device. It would not fit in the case with the motherboard and everything else finally seated in. I had to make some modifications to the case to allow it to fit. Luckily the mesh cover on the top is removable... I took that off, attached the liquid cooler and used some plastic to raise up the mesh from the case itself about a quarter of an inch. I had to use some nice looking tape (oxymoron) to attach it to the case. It looks ghetto rigged if you look closely but it isn't noticeable from a distance.

3 out of 5 eggsExpansion Slots Don't Line Up

Pros: - Cheap
- Spacious
- Lots of fan spots
- Decent Quality

Cons: I have two minor problems with this case:

1. The sides of the case have a tendency to warp which makes putting them back on a hassel.

2. The expansion slots don't quite line up with my graphics card. The frame of the slot overlaps with the HDMI port on my card slightly which makes it short out when the HDMI is plugged in.

Unfortunately this has prevented me from being able to connect my TV through my graphics card. I was able to work around it by using my motherboard ports but I can't use graphic intensive programs on my TV.

I only took 2 stars off because it's a pretty decent case but the fact that I can't use my HDMI port has been somewhat limiting. This may be only a problem with my case though.

Other Thoughts: My specs:
XFX 280x Black Edition
i5-4690k
Gigabyte GA-z97x-UD3H-BK
Rosewill Capstone 750W-M

4 out of 5 eggsVery good for the price--just a couple issues

Pros: Price is right.
USB3 ports on the front.
Includes higher-end features without the high price.
Plenty of space for any graphics card you could want.
Sides are interchangeable, so if you don't want the fan holes, you can swap sides. I think Corsair also sells the sides separately, so you can buy a solid side and get rid of the holes completely, for a price.
A Cooler Master Hyper 212 Evo cooler does fit.

Cons: Just a little too small in some areas.
Tool-less 5.25" bays more trouble than they're worth.
Included fans are too loud.

Other Thoughts: This case had all the features I wanted, and is reasonably priced. I'm very happy with it, but there are a few areas I'd like to see improved that likely wouldn't add much (if anything) to the price.

1. Add a little more space behind the motherboard. It's cramped to run cables back there. Once you get the ATX power cable for the motherboard back there, you will have to be careful about where you route any other cables to ensure you can still close the back panel. I've had to leave some cables inside the case because I couldn't route them properly and still close the back.

2. The included case fans are too loud. If you're going for a quiet build, you'll need to plan to replace them. I'd rather they weren't included at all and the price were reduced by $5 or so. But, I suppose some people would try to use the case entirely without fans if they did that.

3. I still use 5.25" drives. I've got two optical drives just in case I need to burn a DVD or want to watch a Blu-ray (the Blu-ray drive isn't a burner). These work fairly well with the tool-less system. The problem is with something that isn't full length. I have a Rosewill card reader/USB3/USB2/eSATA device that uses a 5.25" bay but is only a few inches deep. I had to pry off the little tool-less lever and use screws, and to be honest, I'd feel better if the optical drives were put in with screws too. I don't understand case manufacturers' obsession with tool-less bays. What's wrong with screws?

4. The case could stand to be an inch or so taller. You will not be able to fit a case fan in the top front position if you have a full length optical drive installed. If it were a little taller, this wouldn't be a problem. As others have noted, a full length radiator also won't fit for the same reason and because it will likely interfere with your RAM on the motherboard. If you are going with a water cooled setup, I suggest a larger case.

5. No filter for the side fans. Really? No filter for the top either, but these should be exhaust fans so I haven't added a filter to the top, just the side.

4 out of 5 eggsNice airflow design but worse drive bay design?

Pros: A lot of fan mounting options.

Got a very good air flow optimized impression.

Nice black clean look.

The optical drive looks pretty good once its in place, looks very natural once in place.

Water cooling options which is always nice.

Cons: Rather than a slide in and out you have a cheap plastic clipping that easily gets stuck when putting them back in place.

There's no dedicated SSD mount, you could use the plastic things but that just looks so inelegant.

Not too many zip tie mounting points as I would've hoped for

Would've liked a longer HD audio cable since routing it with the other front panel cables through the same hole proved to be impossible as it wouldn't reach the socket in the motherboard. Had to cut the zip-tie and loop it around near the optical drive bay.

The side panel fans are placed side by side, but depending on the graphics card you won't be able to use one of the panels because they would be right in front of where the PCI-E cable would be coming out of blocking the possibility of placing a fan there.

Last problem isn't a problem with only corsair 300r, but with cases in general. The side panels are a FRICKEN PAIN IN THE POOPER. Please please I hope someday someone makes a case that can deal with this problem cause its oh so frustrating seeing a tiny bulge when I close the side panels every single time only to have to restart the process.

Other Thoughts: OK so I have the 200r as my personal case and loved it, so when I was building a pc for my cousin I decided that since the 200r was such as great case that the 300r would've been even better right?

Kind of, but not really. The case is clearly more optimized to move air around the case with the meshed front and the elevating corners. But the hard drive bay just seems to inconvenient having worked with the 200r. It seemed like a step forward and backwards at the same time.

2 out of 5 eggsincorrect dimensions listed by manufacturer

Pros: nice case looks and does everything it says, got it on sale and figured that I would get the 300R for the same price as 200R. more space and great reviews.

Cons: size of case listed at 17.7 height is incorrect. That is without the feet i'm guessing. but as far as I can see they don't come off. height is 18.7" and that just won't fit my desk space. Really dissapointed that dimensions are off by an inch

3 out of 5 eggsSmart Interior, Flimsy Panels

Pros: -Interior is smartly designed and easy to work with; basically everything you've heard about Corsair cases.
-Plenty of locations for fans
-Nice minimalist design
-Front panel ports located on front

Cons: -Flimsy panels are bowed when installed. I came to this case after using one of the old HAF 922 cases, which was a lot sturdier.
-Reset button is ridiculously small
-Headphone and mike ports are not colour coded, not a huge deal, it just helps when it is dark.

5 out of 5 eggsA Great Case

Pros: As my first case, I found that this particular case has a LOT of room inside. This means that fitting in parts is relatively easy, and the same can be said for cable management. It might be a rather basic case, as far as the power button is concerned, but it is sturdy and gets the job done. The tool-free HDD bays are great as well, it makes adding and removing new hard drives easy. All in all, a great modular case that can support some a great PC.

Cons: The side panels can be a little difficult to get back on the case. I actually found it to be impossible without the help of a friend. Aside from that, not much for cons.

5 out of 5 eggsPhenominal Case

Pros: Exceptionally excellent quality case. Tons of cooling options. Water and Air options both work well. This case is clean, well built, durable, and is amazing. I replaced a CM 690 II and I didn't think twice about it. Ive owned tons of cases and this one is a champion by far. And at the price point its perfect, not to expensive, and not to cheap. Fits extremely large video cards, tons of hard drive options, lots of optical space, and cable management is a breeze.

Cons: The only thing I can point out is that Xigmatek 140mm fans have a weird lip on the mounting holes that wont allow the front bezel to seat like it should. Its not Corsairs fault but Xigmatek's, so keep that in mind with your fan options. I sliced the lip off with a razor blade and now it the fans seat perfect.

Other Thoughts: The one reviewer who claimed his Corsair H100 and H100i wouldn't fit, well hate to tell you this man, the website clearly states what will and wont fit. Its not corsairs fault you cant read manufacturers information.

5 out of 5 eggsSolid case for mid end systems

Pros: I have ordered over 5 of these units for lower end servers at multiple sites. The price, quality, space and reliability of these cases have made me an avid fan of Corsairs quality cases. Always pick these units up when they are on sale/rebate.

Cons: The only major draw backs on these cases are their lack of extra 3.5/2.5 bays within the cage and the front audio cable being just a bit of a stretch to plug into my MSI motherboards.
