The only thing that will stop me from buying it right now is the fact that I’ll likely not have time for it for a while. 
Looks amazing and I have waited for an actual STRONG portable gaming computer all my life. I’ll likely fill it up with MAME emulators and whatnot; it’s almost certain to become my central hub of arcade and handheld gaming. No offence to my Switch. 
And yeah it looks really well done. I also plan to be backing it up (completely) to my NAS from one point and on!
