Apart from HTPC specific cases, I wouldn't consider having a chasis in my living room, until now.
Make sure the MK2 has a bracket so that it can be hung on the wall - that thing is a piece of art. Reminds me of the B&O wall mounted multi CD player(BeoSound 9000).
Slot for DVD in roof - I like that idea. Also maybe a way to stealth the rear i/o & PSU cables so that they all exit together at the bottom rear - out of sight.
I'd be happy to be a Beta tester - it looks awesome.
