That is a rather large case to have such small parts... I use a Silverstone Milo ML03B for my living room HTPC. IT holds two 3.5" drives (4TB) and a full 3.5" BluRay drive which I find a lot more convenient then pushing in a laptop slim drive and clicking down the media most people don't like to do. Plus regular PSUs, etc. It has plenty of room and cooling and also holds my CETON PCIE card. Also USB3 on the front, etc. $65 from the egg.
And it's the same size exactly as the other devices on the shelf. This box would be the same height but much narrower looking out of place to me. Maybe that's just me.
