FWIW (mostly from my shady memory & a visit to sunsolve...)
The 2000 is an E280R in desktop form. That means FCAL disks and an
integrated FCAL controller. Also a SCSI bus for the CD-ROM and an external
SCSI port. Those could be useful. Its ethernet is eri0, 100Mbit.
The IIIi, IIRC, has an integrated PCI and IDE controller. It has SCSI disks,
but the CD/DVD is PATA. The 2500 a V240 in a tower. The U45 is a V245 in a
tower. It has SAS.
I think they (2500 & U45) had the 1st CPU integrated with the motherboard.
The 2nd was a daughtercard. They may have the logic for the four integrated
gigabit ethernet ports but they only have the RJ45 soldered on for one or
A loaded U45 is the "cadillac."
If you go the 2000 route, stay away from the 750Mhz CPUs and shoot for the
1.2Ghz if you can. The 750s have a pipelining bug reminiscent of the Intel
Pentium fp bug.
