Alright, here's my question. My roommate's 360 just got the RROD, and he's thinking of just buying an Arcade model to replace it. Thing is, he's not sure about whether or not the Arcade stock stores have will have the new GPU/CPU/heatsink fixes or not, and he doesn't know what model (Zephyr, whatever) they are. I don't have much of a clue either, so could somebody explain how to tell (preferably without opening the box) what specifications the system inside will have (aside from the HDMI/non-HDMI status; that's easy enough to figure out)? Thanks in advance for your help!
