    The case is a pleasure to work in! With lots of room to work with it can make a novice PC builder's first time way easier. This case can support up to 7 120mm fans making airflow great! As for cable management behind the case it is quite roomy and easy to work in. A thing to watch is installing fans on the top of the case, I found it quite difficult to get the fans flush with the mesh surface, but after some perseverance, I did it :).

    The case is pretty enough, and has almost all of the features you would want. I replaced the original side panel with the more attractive solid-window panel of Corsair's Obsidian 450D. Unfortunately, despite having mountings for dual 120mm and dual 140mm fans at the top, it does not fit the Corsair 115i 280mm radiator I bought. Had to do some jerry-rigging here. The front panel has room for two 120 or 140 mm fans, and the 4 quick release hard drive bays are nice (compatible with 2.5 or 3.5 inch drives).

    Personally not enough room not the cases fault though, love the filter space in front so my intake can really breath and airflow is great highly recommend for a mid tower build.

    This case is surely not the best in materials, but you can put a GPU long up to 450mm inside! You can also manage the cables pretty good

    I know it's an older chassis, introduced a few years ago, but the 300R is still a special case to me. Its industrial, blue collar looks got me. It's also got a good amount of features (tooless bays, good airflow, and a windowed side panel to show off your rig). I even managed to get it cheaper than usual. Couldn't be happier.

    Lots of room, lots of spots for fans. Love it.

    The case isn't as sturdy as I read. Its better when everything was installed, but still feels less rigid than my old NZXT Tempest 210.

    I could not mount the Corsair H60 with the fan on the inside. The two 140mm top fans don't leave enough space to mount the radiator fan between the rear exhaust port and the radiator. I ended up putting the fan on the outside of the exhaust. I suppose I lose a little CFM from the grate, but I'm not sure how much that matters.

    Similarly, I was tempted to mount a larger 280mm CPU cooler but glad I didn't because there wouldn't have been enough space to mount that either. The motherboard is too high to fit both the fans and radiator. Similar to the rear exhaust issue.

    Also, the top 5.25" bay prevents the 140mm fan from mounting by about 2cm. I had to drop my DVD writer to the middle bay slot to fit my fans.

    Lastly, the top grate where you mount the fans has pre-cut holes for both 120 and 140mm fans. Once I mounted my 140's I removed the paper grommets for the 120 spots, but you can still see where it was cut. Not a huge issue and you can't notice it unless you know its there or look closely. As I built it, I noticed it, and now it bothers the perfectionist in me.

    It is a nice looking case, and any ONE of these issues I would still give it 4, maybe 5 stars. But there was just too many little issues to warrant more.

    This case doesn't do organization as well as other cases in its price range, but it still is a pretty decent case. I like the see-through panel on the left, and the compatibility for a LOT of fans (albeit kinda overkill, I think). Lots of room for storage, very little room for wires on the right side.

    When my 970 arrived it didn't fit in my original case the CM storm scout so when faced with buying a new case or returning my 970 I chose to buy this case and it has served my darn well with no major issues besides lack of space behind the motherboard tray.

    P.S. anyone willing to tell me how to clean the front dust filter on this thing is awesome!

    Ever since I bought my 300r case it has been a Love hate relationship. I absolutely love the clean but industrial front aesthetic, And the functionality that is expressed elsewhere within the case. It is lovely to build in... However, There are a few things that I dislike about it. The first easy fix for me was to buy some grommets for the case, since the cable cutouts do not include rubber grommets. Lucky, corsair used the exact same holes in the 350D case. So I was able to buy a replacement kit for not a whole lot from Kustom PCs. The next feature of the case which I could have done with out with, And this is perhaps the biggest complaint with the 300r is the windows side panel. It is made from a cheap acrylic which isn't the nicest, But WHO Thought that those Fan Mounts were a Good Idea??, They block the view of the interior, They make the already cheap looking acrylic look even worse. And If I actually install a Fan there, That just makes the aforementioned disadvantages even more prominent. I was tempted to mod the side panel with some nice acrylic or some glass but I never got round to it. Another problem is the top does not support a radiator because of motherboard clearance. My final complaint with the 300R is the poor cable tie mounts in the rear, How much would It have cost them to include just a few more in realy key areas. like for the EPS connector. I did alleviate this issue by making my own cable straps by using the unused standoff threads. But more would have been better.
