I am interested in moding my XBOX and have been looking at the different mod chips. I think since I do not have a lot of experience at soldering I want to go with the Matrix chip. However, before purchasing the chip I want to make sure that I know if there are any difference between the Matrix chip and the XECUTER Lite and Pro (other than they require soldering). Can I perform all of the same functions using the Matrix Mod chip as I could with the Xecuter Chips? For instance, install a larger hard-drive to back-up my games, or copy my MP3 collection to use the Xbox as a home multimedia center? I appreciate any suggestions or comments.
