Two words: Get it.

I'm running mine on an ordinary wall-socket, along with, umm, I dunno.  A
refrigerator, some lights, whatever else is on the circuit.  I'd love to
have some of the stuff the electrician was smoking when he wired this place.
And once, just once, in my life I'd like to live in a house with enough
electrical serivce, wired in a sensible way.

Aye, matey, it is that.  Shipping weight is 300 lbs.  It's a
couple-of-feet-or-so on a side.  Hurts like hell when you roll it over your
toe.  And did I mention is was big and heavy.

This one has 3 HVD hard drives, a CD-ROM, a 150 MB tape, and an Exabyte
tape.  4 processors, 1.5 GB RAM.  That ain't maxed, by any means, but it's
no stripper, either.

Probably, but I don't see it in the Owner's Manual.

My problem isn't the weight, or the size or the power comsumption.  My
problem is finding something for it to do.
