I do; however it does require some special tools. First, you have to
take the cover off, that says G5. There's a little grey post that you
have to take out on the top side, next to the video card. After thats
out (it does take some doing...) pull the grey plastic piece down
that's on the front of the processors. This releases 3 or 4 latches on
the top cover, which slides over to the left, and up. You can then
take the plastic part from the front off. Next, you need a very, very
long allen; I believe it's either a 2 or a 5/64. I have a security
set, and an extender that I got at a hardware store. There are two in
the front, (one on each) four in the middle (these are hard to get to)
and two on the back, one on each. You don't have to take these all the
way out, in fact I wouldn't recommend trying. They are wedge shaped
and hold the processors in with pressure on the sides, as opposed to
conventional methods of applying downwards pressure. Anyways, then you
just wiggle them out, and there are some phillips screws to take the
actual processors off the heat sync. Also there is probably a second,
smaller heat sync attached to the back side, with some metal or
plastic clips. It should be obvious how to take it off, as it's
attached to the processor itself. I would strongly suggest being
grounded while you do this; new processors are VERY, VERY hard to find
for dual 2GHz G5's, and may cost you upwards of $800. Hope that helps.
