Alright, I'm new to the Mac world, I need some insight on a few things; I just bought a Pro 1,1 for $100 (BSEL'd Octa-core w' 32gb full buffered ram), it's missing a side panel and all of the HDD bay caddy's; Are newer generation MP HDD caddy's compatible with my 1,1? Also looking to flash a newer GPU (support for Metal), any recommendation(s) on a GPU? Is there a public download page for flashing/doing such things on my own? I will be throwing down El Capitan when the final release goes public and Windows 10 under bootcamp, I'll be seeking for help with this in the near future. Is there any other neat things I should know about this mac? I'm also proud owner of a maxed out G5 quad and DLSD 15.6" Al PB.
