I also have an HDHR, I don't expect problems with that, other than the 
number of unencrypted QAM channels going down fast.

I'm also wondering which distro to build this on, but don't want to ask that 
here for fear of starting a LONG thread. All the major distros seem to be 
quite Myth-capable, so I'll just go with what I'm most familiar with.

I have a server with 4 cores and 16GB of RAM running several VMs, hadn't 
thought of making the new B/E and that server into one box, could save a 
lot of watts that way.

Dang Linux, too many choices, so you spend forever deciding what to do.
