They were the Intel D525MW boards, in a box made by ARK, a subsidiary of 
Intel.  Running an RTAI patched kernel, wit hyperthreading disabled an a 
kernel argument of "isolcpus=1", the IRQ latency is about 2 u-s at the 
halfway mark on the bell curve.

I am of that same opinion, as long as the battery doesn't explode I'm 
fine.  That OEM battery is now north of a decade old so I fully expect 
the in-cord psu will upchuck trying to charge it one of these fine days.

100Gigs.  Hasn't sneezed (yet).

With limited life of the flash, linux filesystems are hell on flash.

My old Asus board does not support that AFAIK.

If I need an offsite, that event will probably coincide with my demise.
At 80, I am well aware that waking up in the morning is an excuse to 
celebrate.  ;-)

At this late date, I think the one box does it all is ok.  The wife will 
probably crawl under the desk and power down the room by pulling line  
cords when I am gone.  And has no interest in learning the technical 
stuff.  So if I am not here, its all moot.
