Surprise surprise, it showed up early.
Unboxing and internal pics. Click for full size:
The unit came without the screws installed. They probably assume anybody who buys one without a hard drive would immediately install their own. Unfortunately, this means that when I pulled it out of the plastic bag, it fell apart. No damage, but if I had been standing up over a hard floor, there could have been.
The outer housing (everything but the front and back panel) is metal. This is surprising (in a good way), because nobody makes electronics out of metal anymore. It seems to be steel. Aluminum would have been better, but it should keep your internal drive cooler than if it had been plastic.
If you look at the PCB pic, you will notice the connector at the bottom of the pic is not fully inserted. I hope this isn't an indication of general quality control.
Included accessories consist of a 12v 3A AC adapter, 3ft USB (A to B) cable, 6ft RCA (composite + stereo) cable, 6ft HDMI cable, remote (batteries included!), instruction manual, screws, a tiny instruction manual, and a T-shirt.
More to come after I actually set it up and try it out.
