My opinion is, if you are not having any problems with anything, don't touch it. I have minimal tweaks that I use on my net boxes as well as my recording boxes. Between talking to Jim Roseberry (
www.studiocat.com ) and examining his build as well as some experimenting from
www.blackviper.com I've been in really good shape.
Just remember, if you decide to mess with anything, make sure you know all your settings. Back them up, take screen shot captures, cell phone pics, anything you can so you always have your original settings. Also, when doing any kind of system tweaks, I've learned that doing one at a time is a good way to do them because if you do too many, you won't know what caused the problem. The same with Vipers tweaks. I may be able to get away with "safe" all in one shot here where if you do it, something may fail. Just be really careful and stay focused while doing any tweaks. Good luck!
