DELNI: 3.25" x 7.75" x 19.25" (h x d x w)
DEMPR: 4.25" x 7.75" x 19.5"  (h x d x w)

Most of ours are on shelves in offices (~72 F).  I doubt the heat output
is very much.  DELNIs have cooling slots on both ends and in the back.
DEMPRs on the 2 ends.  If you're worried about heat, leave the covers
off the rack.  With that, I wouldn't expect a problem unless your room
is very hot.

I have never seen a problem with a DELNI in over 2 years use (we have
5) or with the DEMPR (have 1, installed last winter).  Still, you should
leave plenty of room for cables.  Whenever you change/move/add/remove
a system, you might have to get to them for recabling.

I haven't had to.
