I've had one since June and this thing is incredibly good / powerful as a media server. Between low power draw, the 2x2.5G, upgradable SSD and many USBs, attaching a couple external drives to it beats any NAS on the market by an obscene margin.
It cannot be stressed enough how much Intel did a good job with the latest QuickSync ASICs.
Conversely, this is even more useless than it looks as an actual computer. No DP pass-through means no useful docks. Random latency hangups because of single channel RAM and the 1x PCIe lane to SSD makes even starting firefox surprisingly slow.
