My server is also a 3 year old atom (due to be replaced this year) with 
2 x 2Tb + 1 x 1Tb + SSD.  Last time I checked few years ago, idles 
around 25Watts.  I expect to get significantly lower with this years 
haswell tech.  All my pcs (3 others) boot from iscsi so are physically 
diskless, apart from one which is a frontend/slave has a 1Tb recordings 
cache (which can get replicated to the master as when I wish it to, so 
does not need to be on).  Again frontends are intel based first gen 
clarkdale (due for replacement) but low powered as I dont need an 
additional GPU or physical disks.  I use a always on alix/voyage box for 
always on services - dns, email, tftpboot, ipxe, mpd (with dac), karaf, 
etc this is just 5watts.

My point is with - todays tech - I would probably still go intel and 
just replace the alix with an arm device.   Though I am interested in 
Samsungs arndale, and the cotton candy.  Candy could just be left 
plugged into an amp, to make a always available front end - quite neat.

With repect to architecture (and the O/S & device upgrade cycle) I would 
stick to intel.  Maybe in a years time I might consider replacing my 
main raid/iscsi/web/mythbackend server with an arm solution.

Don't get hung up on the raspberry - it's really underpowered and will 
be very very time consuming now and in the future.   There will be 
better arm tech this year for Myth I am sure.
