Thanks to ASUS, I got my hands on one of these after seeing what appeared to be a giant heat sink fin integrated into the top of the case. This case may be of interest to non-Tinker owners as well, it is not designed like the equivalent Pi cases with a fixed aluminum stud touching the SoC. Instead it has a small aluminum block that has an adhesive side, and a thermal pad side, and is clamped down onto the processor by putting the two halves together. This allows some freedom on the location of the SoC relative to the lid.
First off, same nice packaging the Tinker owners are familiar with:
The case itself is quite heavy, and a nice color/texture, although the finish is most likely not 100% on this one, as it's pre-production
The reason for the weight becomes immediately obvious when pulling the two halves apart:
All I can say about this is, if the thermal pad/adhesive aluminum block fit properly, there is a lot of thermal mass here, and I'm perfectly alright with ASUS calling this fanless. The extrusion is very thick, over 8mm in places. Now for the bottom, a comparatively much thinner stamped part, the embossing does it's work to strengthen the base adequately.
Something important to notice in this picture: The Tinker sits on aluminum studs, and does not bolt down. The heat sink block holds it in place. I have been told that the two additional holes you see here to the left side of the base are for a VESA mount adapter:
I can't verify (no hardware), but the holes are 85mm apart and threaded.
Board fits nicely:
Now, putting it together only involves 1 thumb screw once you've gotten the aluminum block bit sorted out (a little bit of a balancing act, but not really a problem. This would be my only feedback where I think a different option would have been better: The thumbscrew is located at a position so as to be on center with the SoC. This makes sure the whole stack is making contact, but it also creates a pivot point which rattles when you move the case around. Not a problem for 90% of people, to be honest. In my humble opinion, 2 thumb screws, one to each side, making it a bit more rigid once assembled. Oh, I also pulled out some rubber feet and put them on it, none were provided in the box, and I like the grippy feet.
My unofficial testing shows the case very easily outperforming the tiny heat sink thermally, so in that respect it wins. Aesthetically it is a very nice looking product, of course I'd say that should be expected. I'll follow with something a bit more empirical later on.
