You definitely hit the Motherload of WarHammer models. I suggest you read ARMORMAN's Warhammer40K thread. It is the most definitive thread on the subject. Don't forget to post some pictures of anything you have built, we'd like to see your work.
Make sure sure you read the Rules and Policies of this forum here:

After reading the post about pirating you made, you have me a little worried. Also, you cannot Download any models from this site for at least 4 weeks after you have joined. The posting Rules of 10 posts is only part of the requirement.
:welcome1: aboard!
