That's cool!
A streaming PC would be great, I've wanted one for a long time but I haven't bought one. I need a better graphics card before I eventually get myself a streaming PC, but graphics cards are too expensive for my tight budget these days.
I also love to make highlight videos, but I would probably do that on my streaming PC, in case I get one, just to spare my main rig the troubles and disk space. I've never used premiere, but I've never been recording stuff in real life either so. I use Video Vegas for making my videos.
