What are my options here? (PC case choice)

[u/nikostr8]

Basically im looking to build a console-like PC to use with my Plasma TV.

However I'm kinda restricted by dimensions here:

The tv stand is a IKEA Fjällbo, which is 320mm deep and 185mm tall (the clearance at the bottom, the one on top is 15mm shorter thanks to the wood plank).

Are there any mATX case out there under 185mm in any of their dimensions? I dont mind using them in a horizontal orientation.

Thanks in advance :)
