What was the TL and starting point budget? Hard to believe that he could get away with all that on the point budget of an average vault dweller (who should only be around 25-50 points). If you gave your players too many points or starting funds, and didn't enforce things like limits on skill/attribute/wealth levels, LC restrictions on starting gear, etc., then that's partly on you.
But it does sound like you at least reviewed his character and gave him a chance and enough pointers to fix things up, at least. But he just really didn't want to be an average joe; he wanted to be a badass in power armor.

That proves nothing. Reverse-image search sends me to another person's Fallout TRPG campaign:
https://forums.modiphius.com/t/homebrew-welcome-to-the-dominion/14821. So you could've just yoinked it from there.
But I'm not doubting you. Just genuinely curious. Tell us what happened to the guy after the game started? Did you boot him? Take his power armor away? Let him live out his power armor power fantasy?
