Well sitting in Sri Lanka and its a tad warm at the moment so thought I would spend an hour in the AC so logged on to the interweb and stumbled on this:
http://www.build-threads.com/category/build-threads/

Just spent the last hour on it and I haven't even scratched the surface!

Enjoy.

Been on there for a good year+ but its a great site, and yes can take up ALOT of your day,lol
