Actually, only up to 6 CPUs - the system has 4 systemboard slots, but
you need to have at least one I/O board in the system. The E3500 fixed
that particular dumbness by having 5 slots, so you can have 8 CPUs (4
CPU/mem boards) + 1 I/O board, but introduced FC-AL internal drives,
which are a pain in the butt (and make the internal disk bays basically
useless for Linux).
Ethan, I've got some spare E4000s, which can be "desk mounted", and have
more cpu/i/o board slots than the E3000, and internal optical/tape
drive slots (but no internal disk bays, unless you use a "disk board").
8U tall, perhaps? I've even got a set of desk-top side covers for
it -- but of course, I don't have the top or bottom covers. The E4000s
I've got came as rack-mounted systems.
The only real annoying thing about E4000 systems vs E3000 systems is
that they only support the 83MHz bus speed, not the 100MHz bus speed;
and the "clock board" they come with only supports a 4:1 CPU clock
multiplier - so you can only do 336MHz CPUs instead of 400MHz, unless
you replace the clock board with one that does a 5:1 multiplier.

E450s were primarily designed to be servers,
not workstations.
But I know a guy (ahem Doc!) who has a very tasty
workstation-config E450, rather drool-worthy.
I'm hoping to run across an E3000 (pedestal, FC-AL external, SCA
internal drives, up to 8? CPUs in 4? trays...) sometime soon. I
spec'ed and ordered one for Lucent in 1997 or 1998, so not quite
on-topic, but I do know a few have surfaced for free/cheap recently.
That's about the only Sun I'm trying to keep an eye out for that has
a CPU enclosure larger than a 3U box. I also worked with some
E5000s, but that's a lot more Sun than I need in my house.
