I've been trading emails with Eonon on the fit. They're friendly and responsive - better support than I expected by far (professional curiosity of mine). That said, their answers are pretty much what's in the thread - move cables, careful with screws, stuff something under the back to support the weight. Not bad advice just not a magic bullet.
