Few points worth making, I feel.

The SMPS, Arduino and amp module all have LEDs. This leads to a very nice red glow coming out of the case vent at night, much like it was running a load of tubes inside. Though it's more red than orange.

I think Firebottle used these cases for phono stages. They are nice. It doesn't look out of place on top of a what was once a £10K Luxman power amp. That's not where it will ultimately live, BTW.
