My power consumption page might help a bit:

The VAXstation 4000/VLC takes the lowest power but at about 6 VUPS it is
quite slow. The 4000/60 and 4000/90 (BUBBLE) take about 100 Watts, which
is twice as much, but are *so* much more usable.
In terms of alpha, the lowest power I've found so far is the Alphaserver
300 4/266 (TIGER) which clocks at about 100 watts. The Alphaserver 1000A
runs at about 180 watts which is pretty good given the expansion
possibilities (it has a BA356 8 drive enclosure built in).
I'm currently running a BUBBLE and TIGER 24/7 which is a VAX and Alpha
node for 200 watts total.

My VAXstation 4000/VLC has a dead power supply. Plus the BA353 I was using
it on it has a dead powersupply. Those two bits originally made up PDXVAX. The current
PDXVAX hardware is a VAXstation 4000/60 and a BA350 (with 1 2GB
drive). My VAXstation 4000/90 has issues, but I forget what.
MONK is currently a XP1000 with three SCSI buses. The Narrow SCSI drives a
TLZ06, the FWD-SCSI drives a DLT7000 drive, and then the U2W-SCSI has 2 JBOD
boxes with 3 36GB 10k drives each.
I'm thinking something like an AlphaStation 200 4/233 or even DEC 3000/133
with a BA350 and 2-3 4GB drives. That would definitely be a bit more
affordable power wise than MONK and PDXVAX combined. In fact less than 10
years ago, that was the hardware MONK was running on.
Oh, and yes, I have a preference for external HD's. I have a lot of 4GB
SBB's for BA350's and a lot of SCA SCSI HD's, but very few drives I can use
internally without opening up SBB's.
