Well, I'm in! lol It wasn't too bad at all to crack this thing open. Just to be safe for reassemble, I took pictures along the way and threw my screws in labeled envelopes to keep track of where they came from. Power supply is suppose to show up today, so, I will be eager to see if it works.
Also, sitting there staring at this Xbox open made me realize I should have bought an SSD to throw in there. I guess it's possible with a software update. Oh well, at this point I just want the thing to turn on and boot up.
