Fan replacement made easy...not

I had to swap fans in a Enterprise SPARC 250 power supply yesterday.
It's cleverly designed to make a simple task as hard as possible.

The module is ~14 long, ~3" deep and ~5" wide. The 80mm fan is at the
end. It's screwed down to 4 studs coming through the end.

Now, if they were normal screws; changing it out would be trivial, but oh
no, that would be too simple. The studs are solidly swedged into the case
end.

You can't unbolt the fan and slide it away from the end, the main board
interferes. So you remove the 6 screws holding it down; but getting to
#6 means first pulling the line filter. Then you lift the board part way
out and slide the fan off the studs.

I wanted to replace the 80mm/1" thick fan with a 1.25" one. There's
spaceI for it but I needed longer bolts. I finally managed to press out
the top two swedged studs and used 1.5" long 6/32 machine screws.

It's all back together, but grrrr...

Heh, try that in a V20Z then you will learn the power of cursing, and
the strong desire for supplies of Band-Aid.
