I've invested in a Mac Pro 1,1 and I'm exceptionally happy with it. I currently have 5GB RAM(plan to upgrade after a while), and the original dual 2,66GHz and 8800GT I think it is. I've bought a refurbished WiFi card, but I'd very much like to buy a new one that supports 802.11n and I'd like to buy an internal bluetooth-card. My first question is: Where can I get these two cards pretty cheap? I've tried eBay, but I don't know which serial numbers work with my old mac. My second question is: Which USB 3.0/Sata 6Gbps card will work with my mac? My third question is: Which graphics card do you recommend(specifically)? I've looked at the 5870 1GB from XFX, but will the 2GB version work too? And where do I look for Mac Firmware to flash the card? My last question is: Which CPUs can I upgrade with? Do I need to flash to upgrade the CPUs? I'm kinda new in the hackint0sh theme, but I used to build a lot of computers back in the days, and now I'm all interested again after boring myself with laptops for a few years.
