I've built three computers in this case now. It's a dinky, compact mATX case; and if you like addressable RGB fans, you have everything included here without having to pay extra for fans or controllers. The fans are static speed, quiet, and RGB is controlled by the reset switch with all the modes you like.
The front-side and front panels are tempered glass, and the front panel does have some unfiltered open holes for airflow. I'd rather not speculate on how much air actually gets in.. and i moved the fans back behind the mounts to allow more air to be brought in, but it's a significantly better design than the CiT Tornado; which has no airholes nor a gap at the front of the PSU shroud to allow for a radiator or fans to be mounted behind the horrendously designed mounts..
Back to the Flash, the hard drive has to be mounted to the floor of the case, and the SSD to the rood of the PSU shroud. If you have SATA power or data cables at right angles, this is a problem. But i dare say there probably isn't any more room for a HDD cage.
Overall a very good value case for the money. And a friend of mine did manage to mount a 240mm radiator in his.
