BillK, which Jetway board are you using? I'm looking at the JNC98-525
for a FE/BE with an SDD for s/w, 2xCaviar Green HDDs in Raid 1 for myth
storage of audio and TV. I want low TDP, hence the SDD and Caviar
Green. Usage: music and recorded HD TV @ 1080i. System will 'sleep' on
RTC until a recording is due to cut down on power and noise (even though
it will live in its own "server room", ie cupboard under the stairs,
which also houses a GSHP).
