The H7 Flow stays true to a traditional mid-tower design while adding bottom fan support for direct GPU cooling due to the vertically oriented PSU. Unlike dual-chamber cases, this keeps the footprint narrow and takes up less desk space. Ultra-fine perforated panels are optimized for airflow, and it's equipped with three 120mm front-mounted fans for out-of-the-box cooling.

Spacious case with it being dual chamber. It's huge, so expect that. There are self retaining thumb screws for the top and two side panels that make removal pretty easy. The mesh panel in front of the 3 stack vertical fans is retained with 1 phillips head screw, and slides right down into place - you can also remove the fan retaining cage from the case with 2x phillips head screws. The front glass uses 3x phillips head screws and slides into place, though you probably won't be taking those off often. The case has room for nearly any configuration you can imagine. Currently, I'm running a side mounted AIO with a push/pull configuration, 3 bank of fans mounted on the top and bottom of the case with an exhaust in the rear. My MOBO is an MATX, so it gives more room, but doesn't even need it, really. Cable management is super easy as well as there is a swing type panel that lets you hide fan controllers, usb extensions, etc. The only thing to watch out for is when using 140mm fans, if you have odd connectors like lian li slide/lock type, you might have to alter the footprint of the connector to get them to fit. I just use 120mm, no headache that way.
