I have now assembled two systems based on the Zotac ZBOX line.
The first is a HD-ID11 acting as combined backend/frontend
with 250GB internal hard drive and a single HVR-950Q USB tuner.
Works perfectly -- silky smooth Advanced/2X playback during record/commskip.
The second is very similar, using a Zotac HD-ID41 nettop.
Slightly faster CPU, plus USB3 (not used yet), otherwise pretty similar.
Again, a single HVR-950Q USB tuner and running combined BE/FE.
Both are tiny systems that can use the included brackets to mount
behind a TV or monitor, and are perfect for basic PVR and video playback.
Storage on both is expandable, with a larger capacity internal drive
and/or more fast external drives over eSATA, USB3, and/or USB2.
I tested record/playback over USB2, and that worked quite well.
The number of tuners can be expanded, probably up to 3-4 USB tuners,
but the bottleneck would then become horsepowe for commskip flagging.
Of course, the same boxes would make great FE-only machines too.
For TV, they're as future-proof as that new LCD screen in the rec room is.
More so, actually, since the TV really only knows how to deal with MPEG2 TS.
