Your hardware spec sounds pretty good, the 430W supply is definitely
enough but I agree efficiency is very important, and it's tough to
find a well-made efficient supply under 400W.  I'm also running a
430W, unfortunately I couldn't find anything less that seemed good
quality and was 80+ certified, etc.

The only thing I'd consider is getting two hard disks instead of just
the single 1TB one.  Get a fast disk for the OS and database, and a
big disk (speed not critical) that you can dedicate to recordings.  I
am using a 2TB WD "Green" drive dedicated for recordings and a Seagate
7200rpm disk for OS/database/networked storage.  This is recommended
to reduce contention between recording and database access.  Also, 1TB
tends to fill rather fast -- my 2TB is already full.

The HD Home run has a built in IR receiver that works reasonably well.
 I'm using it with my combined fe/be with a logitech harmony remote
imitating an MCE remote.  I really like the harmony because it can be
programmed to put everything at the right settings.  The downside is
that it's a pain to get programmed correctly and has terrible
windows-only software to do so, but now that I've got it working it's
great.  It's the only way my wife is able to use mythtv - she just
pushes "Watch Recordings" and it turns on the TV, sets it to the right
input, and brings it to the recorded programs screen.
