No idea. Mac shows zero signs of life. Honestly though, I've done little to arrive at this diagnosis, other than read a few suggestions on the web.
Pretty sure I removed the hard drive. Forget how much ram this thing could take, but I know it's maxed, and for some reason I remember 32 gigs. But it might be 16. And it was the one that had dual graphics cards (one for low power consumption, one for best performance, switchable in system settings).
You're more than welcome to have it. If you spend 10 minutes on it and end up with a perfectly functional computer, I'll take a 12-pack of PBR. : )
