I thought it looked pretty attractive? Small, understated, something that would fit in pretty much anywhere without clashing. It doesn't have anything resembling a "gaming" aesthetic, which is a huge plus in my book.
It doesn't have to be all gamer RGB, but, for me, it has to look well-designed, e.g., like Apple products. The Steam Machine looks fine, but the controller looks cheap and all the buttons seem too far away from each other, as if it's meant to be held by someone with large hands.
Nothing really looks like Apple products except Apple products though, so you are locking yourself out of buying pretty much anything except Apple with this idiosyncrasy. Which I'm sure Apple is quite pleased about.
