I want to pull the trigger on this but need to be certain it will be bootable in my Early 2008 MP 3,1. Can anyone tell me? Also, if bootable, is there anything I need to do to set the Mac to boot from the pcie ssd? I will be doing a fresh install of a later OS. Additionally, I'm upgrading my GPU and they are so thick I want to know that I'll be able to fit the SSD, the new GPU, most likely an R9 280x and a USB 3.0 card in my slots. Will that all fit in the appropriate slots? Thanks!
