I've built several systems in rackmount cases over the years, but this is the best one I have built-in for the price, considering this case is affordable for a home user is very good. I had plenty of space to build in, route all the cables, and install the fans. I was using an ATX motherboard, GTX 1070, and a 240mm radiator which is from the AIO water cooler, the only complaint is that the holes for the radiator screws did not line up, but that's to be expected as they are cut for fans. Overall I am very happy with this case. The case was very well packed and did not have any marks on it when it arrived.
To give some background, I was after a case that had decent cooling for a bunch of high capacity HDD's for running a VM lab/Plex server at home. I don't have air con and with the recent weather in the UK my current case wasn't cutting it in terms of cooling. So far I'm loving this case, it has very solid construction without being too heavy. I love the inclusion of dust filters on the front and USB 3.0 it's not something you see on a lot of rackmount cases. There's plenty of space for all the components and you can easily fit a decent height CPU cooler inside. The only slight negative for me is there are no instructions for mounting things (tbf it's mostly self-explanatory).
