We received the H8DAR-8 unit a little over a week ago with dual Opteron 
275s and it has been running well since.  I didn't have any problem 
installing FreeBSD 6.0-BETA1, and I ran "make -j12 buildworld" 
continuously on it over a weekend.  It finally crashed on an sbfree 
call, but I'd chalk that up to BETA1.  It's been solid under a lighter 
load since.  I like the board and I'm glad Supermicro was able to cram 
it into a 1U case :-)
