I also think this is great, it was the first thing I looked for when I found this forum, but instead I just read everyone elses check out my new build threads and learnt what I could from them. AVSforums in their HTPC forum has something similar that gets updated. You will still have a lot of "tell me about my build" posts... (like the one I posted today, ha!) but I believe the stickie with a few different basic builds would be a great addition to all the helpful info on this forum.
