haha, kinda looked like an IBM T42 rack when all the 1U spacers popped out.
At least the couple of servers were at the bottom - an end-over would have been really funny.
I sincerely hope for the client's sake that was a lease return and not a move.
ETA Looking again, it's not an enterprise rack based on the top vent. Don't recall what the lighter (x86) racks had.
Also looks like a delivery as they were walking away with packing material. Ouch.
