It is far more complex than any mere mortal wants to undertake. Many issues around the internal airflow and temeprature mean it is far from easy.
You should buy a used 2009 or later or a refurbished (good as new) Apple model instead. The memory on 2009 and later is so much cheaper you can justify the purchase in what you will save in memory cost.
If you are a developer, there is a rather complex way you can run EFI-64 in RAM. But it is not simple enough or trouble-free enough for regular Users.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

Easier to build a PC and hack or use the same tools they use to boot strap 32-bit to boot 64-bit kernel, which could have been done, was even, but for some reason someone felt wasn't worth it.
I have 64-bit drivers and kernel on MacPro 1,1 - running Windows 7 and 8. But not OS X (and no not interested in ML one bit, and most 2008 owners are fed up with 10.8.x as well). Love the hardware for the most part and may buy another Mac Pro, but not to run Mountain Lion.

Sell the computer and buy the one you need.

I agree, see it and buy one you need. If all goes wrong you it will have cost you on the parts and you will still need to buy the right Mac Pro. A job like this is really for an experianced engineer. This is not a job for a start out Mac customizer.

Then I will stick to my original point. This is not a job for a start out Mac customizer.
