Per Char Jackson:
Fully
populated with 24 drives, that thing is going to weigh around 80 pounds. Add
plywood and it only gets worse. You'll want to consider putting it on
wheels. :-)

Oops....

My Honda 2 Kw generators weigh about 45 pounds each.... and I know from
experience that 45# is about my limit for carrying something around in
one hand.

Wheels indeed....
