I think a 18.4" display will be problematic as it's not a common monitor size. CMIIW the core concept for this project is not to 'fit the most powerful components possible' but to enable users to customize their Convertible-PC with off-the-shelf components.
An uncommon monitor size IMO is a...
Considering this case/machine setup won't likely be cheap and targeted at those who know and appreciate computers and its components, I suggest just go full blown mechanical keyboard. That way the keycaps are replaceable, fitting with the overall concept of a full-customizable notebook.
Looks absolutely brilliant. This form factor might turn out to be the natural evolution of SFF: balancing between true portability (which laptops have) and customizability (which desktops have).
My two cents would be to thoroughly consider the keyboard and monitor, as they are the two things in...
Since we're discussing TopHats, I personally believe the Ghost S1 only needs the option of a 28.5mm M-Tophat. One hat for extra fans and drives, two stacked hats for a radiator.
Not that I'm complaining about more options, but a single type like this should be much easier for the LOUQE guys to...
57 screws seems pretty insane, especially for a unibody design. Not only it potentially complicates the building process, it also can turn into a logistical nightmare for you.
I can understand 11 screws for these:
4 for the PSU
4 for the Motherboard
2 for the PCIe Riser
1 for the GPU Bracket...
I've built inside the V3+ which probably has the worst airflow of all their cases, and even then I could still game pretty well (albeit using a lower-heat GPU).
Compared to that case the U1 Plus is heavenly. I'm sure your 570 will do just fine.
I've built inside Jonsbo many times before (for me and for my friends) and I've got to say that the company tends to make their cases looks first temps later.
That doesn't mean it's bad, though. Cooling can be adequate as long as you plan for it. Here are a few things you can (and should) do...
I'm pretty sure dual 120 AIO is in the < 5% minority. Experimenting with a more common setup is better worth your budget.
For example ... acrylic / tempered glass side panel? That'll get a lot of attention.
