I’d personally like to direct you to what I’ve been working with some lately, which are LED video matrix walls. Whatever kind of budget you want to throw at it would be fun to see how it turns out for gaming and other applications. I mean, how many people have been to a concert lately and thought, but can that giant screen run Minecraft?

So I have a Windows 8.1 pro key that I'd like to use, but I can't find an 8.1 pro .iso file on Microsofts downloads. They currently have downloads to 8.1, 8.1 K, 8.1 KN, and 8.1 N. What are the differences between these? I'm assuming that none of them are 8.1 pro... So what are my options?
