Yes! Brilliant! And marketable!

Maybe this heatsink should be called "aBsink", if my bad English doesn't make it sound bad
Can anyone reccomend a KVM switcher? is/ was there a good one to look out for so that I dont have to use a pc one with lots of turnarounds...
@GaryN That's a good point with regards to the processor height difference in the MDX, in terms of getting the copper heatsink to do its job properly. However, you should still be able to use it properly for both CPUs if you add copper shims (one or multiple). Using 7448 and 7457 processors, and/or interposer boards, instead of the usual 7447 or 7455 with MDX and stock daughtercards also leads to those kinds of height concerns. The opposite is also true: Washers/spacers also help with when the CPUs are too high for the heatsink. Quoting one of my linked comments:
What's equally as remarkable is that you would think after all that, the G5 would have been whisper-quiet. Oops…
"I have a lab of 17 Dual 2.7Ghz G5s that are all now leaking their coolant- all at once. A significant number are dead in the water and the rest are just holding on right now. Symptoms are wide-ranged but will include fans spinning wildly, machines shutting down when they heat up, greenish liquid leaking from the case, and if you are able to look, crystalized liquid forming where the CPU meets the heatsink as well as corrosion of all the metal surrounding the CPU module. Eventually, the machines just stop working altogether necessitating a replacement of CPU, Logic Board, Power Supply, and two smaller parts. In one case the power supply started to shoot off black smoke and then died.
"As of yet, Apple has been fairly unresponsive in fixing or replacing them and I am now working on making this more public. I am curious to know if any other people are having this problem. I know of 3 other cases outside our own lab here. The machines in our lab were the first of the dual 2.7s- they were bought right when the came out."
Maybe call it an "iSink"… after indibil’s original approach?
It isn’t pretty (yet) but the first “replicant” here is finally complete.
I messed about with USB and FW drives before learning that neither of these will boot!
