I'm doing an RA80-like thing soon. Actually an R80, going at the
bottom of a half-height
rack for the 11/730. I am building that one up in the rack. No way am
I lifting it
fully assembled (and actually DEC suggest you remove the HDA first).

Maybe I have more (unjustified) confidnnce in my abilities to get
things back together
again, but in my case I think I would feel there was less risk of
damage if I took the
thing apart than if I tried to move it assembled. I wouldn't touch the
heads or positioner
parts (A full alignment would be 'interesting') but I would certainly
remove the spindle
all PCBs, mains transformer/PSU parts, blower, etc.

Get more strong friends :-). Be warned that unless they have experience in
moving classic computers you might regret it,
