I was thinking that, just have it be the meat of the sandwich. I just got the RVZ02 last year and the SFX. So the person that halped me with it may get mad I have linux on a 3.5 no room for that though.If redesigned to fit a slim ODD it could go inside the GPU/mobo sandwich so it doesn't block the meshy external panels.
I wish shuttle would do just cases also. I have lots of case ideas, but not the money to pay for it. Like I think a sandwich style in a NES case would be awesome. Fit 1 in a c64/c128 keyboard case & put a flat keyboard in where the original keyboard went & plug in the USB to a front MB header with a adaptor. That 1 is a little ify though.used to love my old shuttles back in the day perfect for a desk and so portable
