This is my mac pro 1,1. Unfortunately the Bios is 32 bit so i cant update it to the newest MacOS which is sad because it is still quite fast for a about 9 year old computer, i have done a lot of upgrades onto it because my dad has a mac pro 5,1 and i can get all his spare parts when he upgrades his, because his mac pro 5,1 is still supported by OS Mojave. That is also how I obtained the second graphics card, because my dad upgraded his graphics card to a metal-capable one so he could update to OS Mojave. I can't tell the exact specs because i dont know all the specs by heart and I am not home currently so i cant do about his mac. What I do know is that it has 14 gb of ddr2 ram right now 1, but soon two HD 5770's 4 hard drives and 2 ssds, a 8 core xeon, so quite a lot has been modified on this thing, the person I bought of ebay from for 50 bucks (this was a really good deal so i couldn't say no) installed the HD5770 because that card doesn't come with this model of the mac pro 1,1. Even though it's old and doesn't run a lot of stuff anymore its still great for backing up my laptop and running Virtual Machines (yes its fast enough). Honestly you can never have enough hard drives. I hope I structured this paragraph in a understandable way, and I hope its old enough for this thread. I also hope I didn't screw up the specs and list something wrong, I am just writing this off memory and using the photos I have because I'm not actually home
