    I've just noticed my 2012 Mac Pro has a bead of white silicon along the edge of the heat sink. Correct me if i'm wrong - I'm thinking Apple has added this as a tamper indicator. Alternatively, could possibly be to stop arcing of components and heat sink in that area?

    Has anybody seen this before? Is it on 2010 models? Anyone with a 2012 have similar sealing of the heat sink?

    Nanofrog - It was said in a previous thread of mine that the retention mechanism on the 2009 board is different to that of a 2010/2012 board Lidless V Heat spreaders. My board (most definitely from a 2012 machine), has a marking '2009' on the right side of the image. Any significance?

    Only the 2009 DUAL CPU board has a different retention mechanism then the 2010 and 2012 DUAL CPU board.
    I dont know if the 2009 means that it is a board from 2009, but its very likely. Wouldn't matter though because the boards fro 2009 and 2010/12 only differ in terms of firmware. Apple could have updated the firmware on left over 2009 boards to use in newer machines.
    You definitely have a CPU with integrated heatspreader since its a single CPU board. So upgraded to a more powerful CPU is very easy.

    No that's just a thermal pad. It's taped [using thermal tape] to the heatsink, but not to daughter board. It's also there so those chips on the daugherboard do not short out when it's touched by the aluminium heatsink.

    What's the consensus on upgrading a single quad core to a more powerful processor? If I wanted to purchase a W3580/90 for instance, would it be better to pay the upgrade cost at purchase with Apple, currently £400 or buy and install myself for approx £400?

    Benefit of having my quad left over but warranty is void unless swapped back without notice...

    selling the quad afterwards makes the upgrade quite cheap.
    i'd prefer having the quad left to swap back when something happens.

    Is the quad desirable or likely to sell at a low price?

    If you prefer to have the quad to hand, how does that make fiscal sense? I understand you might sell when warranty is no longer an issue but deprecation erodes the financial difference between direct with Apple vs upgrade.
