Audio HTPC Case Recommendations

I am looking to build a new audio pc for a home gym so I am in the market for a new case. I haven't kept up on much the past few years so I am not certain what is around now days. I looked on newegg and found a few Lian Li's that may interest me but I would like to see some other options.

I am looking for a black desktop case that is a similar form factor to a stereo receiver. I would like the front to be made of metal and look rather plain. I do not need a drive slot but it is acceptable to have one. I would prefer a classy look to go with the other equipment.

I will be running a motherboard and cpu, no expansion cards. The only drive will be an SSD and media will be accessed via network. This will be a pretty basic system, so the vast majority of the case will be empty. I would prefer microATX form factor so it looks similar to the processor and amp. I could go mITX but I think it would not look uniform.

Cost does not matter, as long as it's not insane. This will be supplying media to a Emotiva UMC-1, Emotiva UPA-2, Axion M22v3, and dual Rythmik 10" subs. The audio stand it will be going on is a Sanus Euro 3.

Any suggestions?

Silverstone GD04 or GD05

Do you have any other hardware you intend on recycling? If not, why not just use something tiny like a Zotac Nano?

Building a complete PC only to play music? This sounds like complete overkill. Why not use something designed for the purpose, like a Sonos, or maybe a Roku-type device if music playback can be managed via some means other that a TV (e.g., an iOS/Android app).

Yeah, they won't be the standard A/V equipment form factor, but this should really be irrelevant. Hell, if the device is small enough it won't even be seen really.
