The T1000 was designed with clusters in mind; Sun originally pitched them to us 
as 'horizontal blades.'  And if all you really wanted was sheer CPU power, then 
having two of the T chips in 2U instead of one is somewhat worthwhile.

In that format (single PS, one 5.25" SATA that's a bit hard to replace) it's 
not exactly what we'd want either.  You can combat most of those deficiencies 
though (in particular there is a little-known kit to change the internal disks 
to 2xSAS).

We have one T1000, as a QA box, but we settled on T2000 as the standard 
afterward due to the extra drives and slots (and the two PS - most of our 
systems are setup as semi-standalone).
