Complete newby

Hi,

The laptop I have is starting to get quite tired and I was planning to make an upgrade to a proper computer. I wasn't planning to build a SFF first, but after looking around and trawling through the forums on this site I got hooked. It's really quite hard to decide what case to build in though. I might move internationally quite soon so something that would fit in a backpack would be ideal.

If you got any pointers from a complete newby it would be greatly appreciated, and if not see you in the forums!
