I got a good deal on a mid 2010 ( actually 2011) 5,1 about $190.00. It has no hard drive or GPU. My question is, what is the best way to load High Sierra once I install a new hard drive and should I start out with a 5770 GPU (originally out of a 5,1)out of my 1,1? Ultimately I plan on using an RX 560 or 580 for a GPU but I think a boot screen would be helpful at first. My MBP loaded High Sierra over WiFi after repairs from it crashing but I don’t know if the 5,1 will do that even though they are the same age.
