Another query. The foam filter that sits in the front of my 11/24 CPU is
clearly badly degraded and needs to be replaced. What do people replace this
kind of stuff with? I guess it mustn't be too fine, this mesh seems quite
coarse.

Hi Rob,
FWIW, I've used 3M Filtrete (?FAPF-UCTF2PAMZ) for this application on an 11/34. It
seems I tighter weave than the old foam, but is designed for pretty high airflow and seems
to work well.
It's about 1/8" thick, slightly compressible, easily cut to size w/ scissors, and
adheres well to velcro hook tape.
cheers,

I think the original is something like 30 PPI reticulated foam.
