THE RM1 INTERIOR
The interior of the RM1 is very simple and quite spacious if i might add (for a case of its size).
Unfortunately other than the fact that the 120mm fan can hit up to 15dBA at load we don't have its specifications.
If you decide not to use a 5.25" optical drive nor a 2.5" drive this bracket is entirely removable.
The 5.25" ODD cover is held in place with a thumbscrew.
There's another support bracket on the other side held in place with two regular screws which you will need to remove if you decide to use an ATX mainboard.
