    I've built 5 PCs so far, some much bigger than the PC-O11, some much smaller. This was by far the best case I have ever built in. As someone with larger hands, it is hard to get into small spaces to manipulate small parts sometimes. I never had that problem with the PC-O11. There is always a way to get to where you need to comfortably, whether that is through the front panel, or either side panel. Not only is it great to build in though, it is also one of the best looking cases I've ever built with too! This really is the best case overall, as long as you are at least using an AIO for your CPU.

    I love everything about this case. It’s my first case upgrade for my personal rig since ~2003. Yes, it’s been a while! Sitting slightly wider than the average ATX full tower, this case has the PSU behind the motherboard. My most recent build besides this one had the PSU below the motherboard, hidden behind a metal shroud, but wire management wasn’t as convenient, in comparison to having the PSU behind the motherboard.

    The case is also designed with water cooling in mind, so much so, that completed build posts with the PC011-D it dominate the /r/watercooling subreddit. With space for more radiators than you will ever need, wire ties, rubberized wire grommets, the side and front panel tempered glass, USB-C support, fan meshes, rubber feet… the list goes on. All-in-all it feels like a really good case for the value, and looks fantastic. It’s a case that will showcase your components and build quality. Do note that the case does not come with fans, but as it’s used frequently in water cooling rigs, most people will be buying their own fans anyway.

    Happiness with purchase: 10/10 - To reiterate, I love everything about this case.

    This case is a godsend. It's quite hefty but it needs to be. It's made for water cooling/custom loops in mind. It's showy and generous with areas for cable management. Has an addition spot for another PSU if your system ever calls for it, however, in the meantime that space is occupied by storage. Despite not having a front intake, it is quite cool with an AIO and fans set up.

    AMAZING CASE. I cannot stress enough how premium this case looks and feels. Not a single sharp edge on the thing, cable management is a breeze, and thermals are insanely good. The only issue I had with it was that the front panel usb header was too short to reach my motherboard's USB 3.0 header, and, even if it did reach, it stuck out too far and interfered with one of my bottom fans, so no front panel usb for me :(

    Beautiful case and cable management for this 1st time builder was a breeze! I highly recommend it!! I am currently running an air system and will make the jump to liquid cooled soon.... which is what this case was made for in my opinion.

    I build a lot in this case. Since I bought it a year ago I drastically changed my current build several times. Saying I know this case maybe more than someone who build once in it and it's done. That's why I give 4 stars. The build quality has its deficits here and there. For example the two screws holding top panel get loose after a while, the rubber feeds could be mounted with a screw unfortunately they are only glued which makes them instable when you move the case a few times over any surface. The glass panels could sit more tight too, there's a significant amount of noise you can hear from the inside. I could go on with that list even longer but I stop here. In the end this case is very good to build in once or twice and to look at. Probably don't rebuild to many times in the same case. Probably Lian Li should've raised prize a little and therefore deliver a higher build quality. I have mixed feelings about this case after one year. I do not get the hype. Sorry.

    I think there's little I need to explain about this case due to it's popularity. It is a great thing to build in. It's not completely without problems though. Due to the screws used in mounting the 3 fans at the bottom, the dust filter will barely hold on to the case anymore as the magnetic strips just aren't powerfull/sticky enough. Top panel would not go back into place at first, reason unclear. It seemed like the screws holding the Kraken X72 at the top were making it more difficult? Not sure, still need to investigate.

    It is a great case! Super-versatile, solid build quality, nice finish. Good mounting system for the glass panels. One of the best cases on the market, hands down. A couple of things to make it better would be to allow at least 25mm of clearance between bottom PCI-e bracket and the floor.

    Some case Lian Li made. A few things that may have not already been said 1. Painting the panels is super easy since they detach nicely without having to remove anything etc. Same for the feet and you can give your case a completely different look in a matter of minutes. 2. there is so much room yet so compact. I am still puzzled after building in so many cases that Lian Li somehow added all this room/potential in such a tiny ATX factor case. It feels that every inch was engineered to just be there to serve a purpose. This is a compact ATX that can hold 3 360mm radiators with a full size video card and ATX board which is crazy as that's something that you normally see in a full tower

    The best case for showcase builds, or just showboating in general. I love this case.
