Agreed, I'd try to resell it even if you lose a little cash. If you're going to spend money on a big enclosure, with a RHP from Pro Products my T10 cost me $381 shipped. Yea I ordered in September and it got here yesterday, but I don't have to worry about anything with it.
No sense in beating yourself up or stressing over it. What's done is done, all you can do now is learn from this and move forward. I would try to sell this even if you have to sell it piece by piece and try to recoup some of your money. Keep your chin up, no one on this site has never made a mistake be it in reptile keeping or somewhere else in our lives. What matters is what you do next.
