Ah, good to know... These are "115V amps" however, aren't they?? (Yep, I
know I'm talking absolute nonsense physically, but you get what I mean...)
I have both a E3000 and a E4000, as well as a couple of U450s. These are
my largest systems right now, with a HP 9000 K100 (PA-RISC) as a close
follower and a HP LH6000 NetServer (dual x86) coming next. For the record,
none of these is in active duty with me right now. The E3000 (equipped
with the "Creator3D" UPA-capable I/O board no less!) blew the switcher
transistor in its PPS1 (peripheral power supply) with a loud bang when
I last tried to power it up, burned out two inrush limiter resistors and
tripped the circuit breaker. The supply is optional, so I think I could
still run the system (with not too many SCA disks in it) right now.
I remember doing a test install of Solaris on my SparcSERVER 1000 (two
processor boards w/ one processor each) in my upstairs bedroom at home
and being already quite impressed by the amount of heat that put out.
The K100 has two impressive-looking radial fans in the bottom and I'm
curious for their noise alone when I'll be powering up that system!
So long,
Arno

I moved from an Ultra 60/2300 to a dual CPU SunBlade 1000. I
suddenly found I could only run my Sun workstation in the winter,
with the patio door open. Even my Dual 2Ghz G5 PowerMac, and Compaq
XP1000/667 AlphaStation put out less heat! Though once it was fully
up it is pretty quiet IIRC (I haven't powered it on since 2008).

We still had Ultra 60's running later than 2008 due to the CAD
software running on them.

For about five years my computers lived in the dining room of the
apartment my wife and I had (before our first child was born they
were in the 2nd bedroom). I had quite a few of those drives running
24x7. We have a house now, and it's nice to have an office that's
virtually silent. The servers live in the garage.

Even with a Sparc 20 heat was an issue. I actually cooked some nice
drives in the Sparc 20 I ran about 10 years ago.
I've been giving some serious thought to bringing up a Sparc 20 in
some capacity, but if I do, the drives will be in an external JBOD,
and the whole thing will live in the garage. It would also be
something that would only run when I want to play with it.

If I were to run one here, I'm fairly sure the input voltage would drop
