Saw this earlier via Analogue Interactive's Facebook page, an owner of the Walnut CMVS unit has submitted some of their photos of it to them.
The unit looks very nice, i still personally overall prefer the original AES colourway/plastic of the Omega Entertainment Machine, though to be honest i couldn't really afford to own either one lol.
Also thought i would take some photos of my personal CMVS unit.
This was built for me by a friend, and probably cost about £150ish after getting a unibios put in and an AES stick.
As you can see it's fairly bare bones, pretty much just a one slot that you would find inside an MVS cabinet with a psu/scart/controller ports coming out of it. I mounted it myself onto a chopping board as i didn't like the exposed wires at the bottom of it lol.
The actual RGB picture quality though is excellent and it does pretty much everything i would want out of an MVS unit.
[Edit]: Just noticed that the Omega Entertainment Machine has now been put up for sale on their official website. There are two packages $499 for the prebuilt one, and $299 for a 'kit' you put together yourself.
Check out more details on their website.
