One thing that excites me the most is the hackability of the "included" case. Enough room for a battery, supercap, switches, normal HDMI ports, and still having free of clutter the GPIO pin rows.

I could also expect a 3D printed detachable LCD bezel/case connected directly to the microHDMI port and GPIO power rails. But well there are already some raspi based laptops for that matter.

I still like the R400 as a "presentation keyboard". Battery pack and HDMI adaptor and it's connected to the classroom projector.

There's surprisingly little room inside- I've been trying to find somewhere to fit a tiny SSD, but without tossing out the heat sink (arguably one of its strengths since it keeps the temperature in check) it's a really tight squeeze.

It's also an absolute horror to get open- no screws, just plastic clips all around the outside edge. First try took a good 10 minutes of prying.

What kind of SSD would be small? Those with a M.2 slot? Or there are actually small form factor SATA cable SSD's? Either way, you would need an extra USB adapter I guess.

EDIT: Regarding the heat sink, with the numbers some reviewers have shown shouldn't there be enough material to shed and still having it working fine overclocked? Granted, you lose the very well designed heat sink, but that's part of the hacking. It was not meant to work that way.
