Re: Kensington system saver hack.

Hi,
  You did not have to ruin the foam gasket on  the IIgs system saver. You could
have probed the foam until you got to the hole with the Philips screw and screw
them out. Leaving the screws in between the case and foam. The gray foam can be
replaced with weartherstripping foam that has a adhesive on one side that is sold
at any home improvement center.
  The older IIe fans seem to be made better (in the USA) the ones for the IIgs
were assembled in Mexico,  they may have bought cheaper bearings, or widen the
specs on what was acceptable for balance.
  Also the direction of the air flow is the opposite of the other. Follow the
arrow picture to see how the air flows. A good pair of wire cutters will work as
good as any dremmel tool also, just a bit more brutal looking when you are doing
it.
Take Care
