Whatever hardware you take down there, please make sure that you get a thin
foam cutout, then a compatible 3M manufactured adhesive that wont eat foam.
A loose structured foam piece is fine and actually prefered as you still
want plenty of airflow.
This will prevent dust from getting into the fans and heatsinks, also, will
prevent insects from getting caught up in there too.
I am assuming that since its for mission work, the the location will be
somewhat remote, this $5.00 foam piece will save some grief most likley.
If you are wondering about the best way to cut a foam section to get a good
shape and cut holes, I have always used a large unbent paper clip fitted to
a soldering iron, but I'm sure theres less crude methods.

Only thing that would need to be done, is make sure someone checks it
monthly, might be able to tell how dirty it is by fan rpm vs ambient temp vs
system temp, since there should be plenty of known values to work with, but
thats not math that I'd like to figure out!

Have fun and send pictures! :)
