Ok, so I bought the computer, had it a day and got my ML download, made a bootable USB and did a clean install. Used Ars Tech and I did get the "Could not restore Invalid argument" error at the end of the restore process. That they say doesn't matter. When I turn the computer on I get to the login screen, I properly log in and then it gives me a black screen. I have to turn the computer off and then on again and then the login screen tells me how I shut down the computer and to click continue or something to open the same apps and docs I had open. What gives?
