Welp, I got mine about two weeks ago. The HDD was unplugged, which I found weird, but it was fine after that...until a few days ago.
I started getting SMART error warnings that the harddrive's death was immenent. I backed up ran a bunch of diagnostics, and tentatively continued to use it for a few days until it bit the dust. Strangely, it can still function if the case is severely tilted, which makes me think it wasn't seated properly.
Started the process for returning with ASUS. By the way, what did you guys use for proof of purchase? They rejected the confirmation e-mail, so I'm printing out the receipt, scanning, and hoping that's good enough. All that came in the box was a packing list : /
