I'm sure you know that the VAX 4000 series are a tad bigger
than the cases you have now - and as such are probably
unsuitable door prize fodder :-) In terms of VUPs/m^3 they
may well be worse than the systems you have now !

A VAXstation 4000-90A works well (a -96 would work even
better :-( ) but you are limited to a single SCSI chain
on those (IIRC).
