Depending on the server build and your physical strength you'll have a lot of trouble lifting it there. My 3U/12x3.5" lives on a cupboard (few inches lower than overhead bins), and I would never dare to (re-)move it (from) there with the disks inserted. Without them it's still heavy enough and a pain to move around, but then I'm more on the nerdy end of the STR scale ;-)
