If your enclosure has doors, they need to be of a type that
allows at least 30% airow through the enclosure (front and back).

Leave a 10.2 cm (4 in.) minimum clearance on all vented sides of
the computer to permit the airow required for proper ventilation.
rEcoMMEnDED EncLosurE
Do not install your computer in an enclosure that does not
allow airow. This restricts the airow and impacts your
computer’s performance, possibly causing it to overheat.
opEn DEsk MiniMuM cLEarancE
If your computer is installed in a corner, on a desk, or under
a desk, leave at least 5.1 cm (2 in.) clearance from the back
of the computer to the wall to permit the airow required for
proper ventilation.
