last round of hardware updates ...
[spoiler=crap you might not want to read]
before:

This is identical to what I have now. I thought upgrading the GPU heatsink would be good enough.

soon to be after:

This is what's in the Falcon (65nm gpu, 90nm cpu). The CPU has a monstrous brick for a heatsink. So, I ordered 2 heatsinks. (One for newly repaired 360, one for the still busted Elite)

Next up, the XCM Core Cooler V2.

I ordered 2 of these also.

I'm going to make sure the systems in my possession (that are out of service contract) are bullet proof. [/spoiler]
