I've never had a problem personally, but it was just that - their first try at a 1u box. > V100 are different beasts again and seem to be designed > with lowest-cost in mind.

The V100 was preceded by the "Netra X1" which was similar to the V100 but had a shorter chassis. The X1 had a V-series front bezel, but was still branded Netra. I actually liked the X1's for their size and price; they were Sun's first "really-really-cheap" SPARC-based server. It wasn't particularly reliable, sadly, but was practically disposable anyway at under $700 a pop. It came out in between the T1-105 and the V-series. - mdh
