I have a modded xbox and i think its time for me to go the next step an install a 160 or 200 gig hdd. I believe i have the excuter 4983 bios but i am not sure if this will allow for large hdd's ? also whats a better choice 7200rpm or 5400rpm drives... I know the difference but i am not sure which one is best for the xbox since one produces more heat. Finally i have slayers 2.5 auto installer can i just pop in the big hdd when i have the correct bios and install it with little hassle with slayers?
