Regarding suck it in cooling.
Well the designers don't just drill holes in the case wherever they
want to get some extra air flow. The air usually comes in, in a
fairly well defined area. In the A3000 it appears to be the front
grill under the diskette slot and the diskette slot itself. So how
about some cleanable filters on the air intake grill and a diskette
drive bezel with a spring loaded cover.
The Convex in our machine room is a big heater and it exhausts it's
hot air, so it isn't just small equipment that gets designed that
way. But I believe that it has air filters on the intake grilles.
Our IBM 3090 is mostly water cooled, and I can't remember whether
our STK disk drives suck it in or blow it out. But I remeber seeing
the maintenance engineer vacuming off some filters and they were 
somewhat largish, so I will guess the were on the intake side.
Of course with filters in place the grill area must be enlarged and
the fan needs to be stronger to get equivalent air flow.
