I'm still unsure about the need for a second unit tbqh - the unit we
have now is keeping everything cool with no troubles whatsoever.

The rack Mark has available doesn't have sides or doors.

As others have pointed out, we could just move the posts on the LH
rack, that presents a problem for the Fugro's, but I'd question the
need to have those after we get troppo running as a VM server.
