Well, welcome abord Gov!
First let me warn, or promise you that this is a hardware hack, you will pull the cover off a few times etc.
There are a handful of people on this BBS that are on the cutting edge...making things happen, then putting the info here for us to read.
So the answer is that all the info is here if it has been done before. There is a very good search function. Just search for the topic you are interested in and you will find the answers.
This thing has been kind of like an online DIY project, somebody does a modification then eventually everyone does it, then someone tries something new and so on.
I recommend you start with this series of posts (7 threads with about 75 messages each).
Once you have done that, start searching for other answers, then once you have done that, join in on some of the conversations that are ongoing.
