Original Xbox Easiest way to mod an OG Xbox?

[deathbyprayer]

Hello! Now, I was cleaning my room the other day and I found my OG Xbox sitting under the bed (don't worry its still on the box, sealed tight) and I would never dream of throwing it away, but I am sure that I won't be playing with it anymore since I've played all 11 of my Xbox games (yes only 11, sad) and buying OG Xbox games is not easy nowadays. So I decided to ressurect it, I want to modify it so that I can be able to play games directly on the hard drive or a burned ISO DVD of the game. Any tips guys? Thanks!
