Fair warning: My high butt is a sucker for RGB.After carefully reading reviews online, I decided to use a Mini-ITX motherboard (ASUS ROG Strix B450-I). Thankfully I did. If you look closely in the pictures, you can see that with a Mini-ITX mobo, there is just enough clearance for the bottom fans and the case cable holes were clearly designed for Mini-ITX. A mATX board would be far too cramped in this case.My build consisted of the H110i Platinum RGB water cooler, one ML140 fans, two LL140 fans, and two LL120 fans (one of which is on the other side of the case, unpictured). With two fans on the bottom and another two on top, a 240mm radiator will not have enough room for the front as the pipes will not have room. If you can get it to work, you will probably worry about leaks given the tight fit. Anyway, as such I decided to put the ML140 fan and one LL120 fan on the bottom for intake, the H110i on top for exhaust, the two LL140 fans in front for intake, and one LL120 fan in the back for exhaust to help keep that area from getting too hot. With this set up, my CPU (2700x @ 4.2 GHz) maxed out at 35.5 C and my GPU at 65 C with GTA V on max settings for 2 hours--with the tempered glass panels on. This was in CA with an ambient room temp of around 72 F. Air cooling or using an 8700K may be a problem though as the fans do have to work harder to move air with the panels on.Cable management can be bit of an issue too depending on your build. The holes provided were great, but I ended up routing all the CPU-related wires through the upper left corner, and the GPU wires hard to be routed over the GPU instead of under to avoid the wires touching the bottom fan. However, some of the messiness you see by the GPU is due to the mobo design as the HD audio pins were all the way in the bottom left corner by the GPU. I also think this is due to how small the case is as well.In the back, you have a 2.5" SSD bay in the upper corner toward the front and a 3.5" HDD bay in the other upper corner. The HDD bay can be accessed from the back (check the pics on the main page) and can also be detached for additional space. The SSD bay can probably be detached as well, but I haven't tried. One issue to note is that while the back panel allows for up to a 140MM fan, you will need to remember to keep that general area clear of wires when the space is already fairly cramped. I would highly recommend a semi- or fully-modular PSU. as you want as few wires in the back as possible. That being said, it's not like you will be playing Tetris at all.The GPU and other possible PCI/-E components are held up by a smaller pivoting panel in the back held up by 2 screws. This panel has a small bump for where the screw normally would be on the components. You will have to hold the heavier components up (i.e. GPU) while re-screwing this panel back in place otherwise the component may be slightly slanted.The case also requires one USB3 connector on the mobo. A mobo with a USB3 connector shouldn't be very hard to find at all, but in case you're going for a serious budget-friendly build, you may find some mobos without this connector.Also, I have often wanted to get the H115i water cooler to replace the H100i cooler since it is 280mm (compatible with the top panel), but I worry about whether or not it would be too cramped with the front fan in place or if it would actually make airflow worse. The case is designed for air to come in from the front and exit through the top, so a larger set of fans would mean intake air will be pulled up much earlier/with more force. In my normal-person mind, I imagine this would make it a bit harder to replace the air in the back with fresher, cooler air or may even create a small low-pressure pocket for outside air to come in. This may be [incorrectly] over-thinking it, but it's still food for thought.The length of the case only allows for smaller GPUs (< 300mm), so cards like the 2070 Duke or similar will not fit in the case.One last thing to keep in mind before purchasing: the bottom has very little clearance. As such, avoid putting the case on carpet and maybe invest in a monitor stand to put this case on. I got the Rolodex 82411 Wire Mesh Monitor Stand, which is just the right side for the case. This has helped me cool my GPU much better, and I believe this allows more air to come in from the bottom even if I had put this case on a hardwood floor or something similar.Beyond all this, this is a great case. I highly recommend this case if you account for all of the above.-1 star for marketing this case as an mATX when an mATX build would not be very good in this case.================Specs:Ryzen 7 2700x @ 4.2GHzAsus ROG Strix B450-IMSI RTX 2080 Ventus OCG.Skill TridentZ RGB RAM 2x8GBH100i RGB Platinum CPU Water CoolerSeasonic Focus Gold 650W
