For me the ability to play games off the HD without having to deal with the LOOOOOOOOOOOOOOOOOOOOOOOOOOONG load times are worth the $$$ I put into the box. It's also one of the cheapest linux boxes, you'll ever be able to build. Plus if you mod, you have a new reason to procrastinate at work and spend time on this forum asking and answering questions.
lordvader129, I did the same thing before I got my chip and you'll be amazed how the early preporation will help when you get your chip, plus you are A LOT less likly to get flamed if you asked questions after you get the chip. Good luck with the mod.
