I absolutely love this. I wish actual 40K still had this kind of character and atmosphere, as opposed to the lifeless, generic dump it took a while back. I cleared out most of my GW stuff other than the board games like Space Hulk and my custom Tru Scale Marines.
I also love old school 40K projects too. I just finished converting a Rogue Trader Dreadnought into a custom Robot for Blackstone Fortress a few months ago, as well as some plastic Squats I'd had lying around forever.
