What can be done with a 2006 Mac Pro
Hello everyone!
I bought a 2006 Mac Pro when it was first released and have been using it as my main computer ever since. It is getting a bit long in the tooth, but given the proper upgrades is reasonably fast and you can get work done.
First, I would go with 3TB Seagate drives, the 4TB Seagate drives changed the screw hole layout which is a problem for the drive sleds.
I'm using 2 3TB Seagate drives in a raid 1 for data, and in the other slots I have two Intel X25 80gb SSDs in a raid 0 for my osx boot and applications disk. Using raided SSDs, even older ones like these, give a tremendous performance boost, I couldn't still use the machine without it.
I have 10GB Ram, cheapest I found was Transcend and it was fine.
You can only upgrade as far as Lion, not Mountain Lion or Mavericks. Unless of course you want to use various hackintosh tricks. This link will show you how to do it.

A final word. 2006 Mac Pro computer uses A LOT of electricity! If I leave the computer on 24 hours a day it costs a significant amount of money here in California, maybe $600 to $800 over a year by my calculation. I turn it off when I am not using it and eventually I will replace it for this reason.
Good Luck!
