If you install your own software on the box from scratch you can do anything you want on it. Have to install linux on it after formatting. IMHO though, if you want to do this a cheap android from fleabay would probably be a better candidate. You can get one with more processing power and memory that way.
I have considered overwriting my os but my wife would be upset with me for years after. Maybe when it warms up outside I'll try so there's some way to get away from the wrath.
