Rebuild prosessor to use OSX Lion

I bought my Mac Pro late in 2007. Production year 2007.

The prosessor 2x3 Ghz Quad-Core Intel Xeon.

Ram is 8 GB 667 MHz DDR FB-DIMM.

ATI Radeon X1900 XT.

Is it possible to rebuild it?


If it is possible to build on, so that I can use a newer operating system. Now the restriction is OSX 10.6.8. Problems with updating the browser and applications.

Is this a good question?

Define what you mean by "Rebuild". What are you looking for? Your systems architecture will limit you.


Thanks for the quick reply, it was complementary. I must consider the new mac pro.

It still makes a good server box as a media server.

Sadly, I don't think there is any 'Apple' hardware you could use to upgrade this baby that is worth the costs.

If you like the case, think about creating a Hackintosh system. Basically you're taking the guts out and redoing it with standard Intel AT logic board with an i7 CPU. Here's a good resource HOW TO: The Perfect Hack Pro (Mac Pro) build using an original Mac Pro case & parts.

Pre-Installed MacOS: X 10.4.7 (8K1079) Maximum MacOS: X 10.7.5*

*This system can run the last version of OS X 10.7 "Lion" if upgraded to at least 2 GB of RAM. However, although it has a 64-bit processor, it has a 32-bit EFI and cannot boot in 64-bit mode. It also does not support "OpenCL" running the default video card or the other build-to-order video cards that were offered via custom configuration. Please also note that OS X Lion is not capable of running Mac OS X apps originally written for the PowerPC processor as it does not support the "Rosetta" environment.
