Sorry for dropping off the map there for a month. Lots of news of future changes happened while I was gone, but it appears that the hardware landscape stayed fairly stable. Keep that in mind if you're planning to build a new box.
Unfortunately I didn't get to address the brand bias in the recommendations though :(.
