Aside from some minor adjustments from the QBX version, the dimensions and overall look is exactly the same except looking like swiss cheese. A standard Mini-ITX motherboard fits like a glove, with enough space to the top, right and bottom for the routing of cables. I’m debating whether to upgrade to a 120mm AIO next as the ryzen 2700x I have in here is power hungry and vertical height for air coolers is something to consider. I was about to upgrade my GPU also along the building proccess, but life is quite rough lately, so I need to save some cash for it and the GPU upgrade is in hold for it, but I don't mind as there will be AMD to show up some new line-ups soon enough, so I stay calm and patience. A few different cable cutouts are available that you can take advantage of, and also a bit of space behind the motherboard tray to hide excess wires.

You will also need a small form factor power supply instead of the expected ATX type or the airflow will suffer.there's always one thing that utterly ruins the case, requiring some extreme modding and wasted time to work around. I can use that PSU shroud vents as I want because I oriented the PSU where its fan faces in rather than out. Nobody likes those situations in which you need to uninstall a game to be able to install another one. Recommend doing this first, particularly if you are installing an 80mm at the front as after you put the PSU in, you won't be able to get to it anymore. inch bay hidden behind the motherboard tray, and you can also install an SSD in place of a slim optical drive.

I wasn’t sure I could get my fingers into that gap to plug the PSU end caps back in, but pre-bending the cables left me just enough room. Earlier I installed 2x 120mm fans with 25mm thickness under the GPU but it snugged the GPU shroud, and its fans grinds the back frame of those 120mm fans and it was bad. I really would like a premium version of this case (without the gaudy sticker or logo- just straight minimalist style, we get enough exposure to branding as it is) with better and more premium materials. It may not be entirely seamless, requiring at least one proper Philips PH2 screwdriver and some prep work in advance, but it is not difficult.I dont take an option to use slim 120mm fans on the bottom, so I'll leave it like this for sometimes. In fact, that’s a major theme of the QBX: it’s almost entirely toolless, and doesn’t need screws in most of the places I expected them.
