The Clevo 651se is rebadged by lots of companies. All the hardware has worked fine with the drivers that came with Fedora 21. The only slight pain was getting the Nvidia drivers but, in the end, I found some BumbleBee rpms that bundled the drivers.
Everything feels cheaper than the Apple laptops but it all works well enough. I've had it for 6 months and nothing's broken yet. The back of the screen is worryingly bendy plastic and the backlit keyboard is literally a light behind a normal keyboard so you won't be able to read the keycaps in the dark. Also all the keys are the same size so it is hard to find the arrow keys reliably.
All the special function keys worked out of the box (Volume up/down, aeroplane mode etc).
If the built in HD display is not enough you can plug in 2 4K external monitors, however if you choose to run all 3 screens you'll have scaling issues until your chosen distro moves over to Wayland(or Mir?). Fedora are hoping to change over next year.
