It is really well made. I had to take the whole machine apart to put in a QWERTZ keyboard and almost everything is easily replaceable and maintainable. The frame feels as sturdy as a typical Macbook chassis, the joystick elements are screwed in and can be swapped quickly, the motherboard and cooling system are also well assembled.

The only thing I hated is that they glued the power button onto the backlight foil of the keyboard. I don't know what they were thinking, but glueing a flimsy flextape onto a flimsy foil is a horrible decision. Granted, most people probably never change their keyboard (but they didn't have the 64GB model with German layout back when I bought it).
