Oh man, I've wanted something like this for a while now. My three main criticisms are:
The bezels are a touch too thick for my liking
I'd prefer a slightly darker finish to make it match my setup better, but again, personal preference
I feel like that top right corner could be filled with something other than a logo, such as more keys, or maybe a slider/oled screen like others have suggested.
Otherwise, this design looks perfect to me and I'd be willing to buy one.
