[Recapped my power supply and installed a mod chip. Just trying to get some idea of where to go from here.]

Hello all, I am new to xbox modding.  I am just trying to learn more about the software side of modding this console.  I have experience modding just about every other console and am now getting into the original xbox.  I've installed an openxenium mod chip, and have ordered a 2TB hdd, ide to sata converter, and 80 wire ribbon cable.  I'm just trying to get a feel for what the current methods people are using as a lot of information is outdated.  Thanks for reading this.
