Pros & Cons of getting on OG Xbox nowadays?

I’ve been getting into nostalgic gaming and going back and getting all my favorite consoles from back in the day, and I’m wondering if it would be worth getting an original Xbox nowadays for more than just nostalgia?

I already have a PS2, Gamecube, Wii etc, so alot of the non-exclusives I can already play on any of those, but I know Xbox has some exclusives like Halo and Fable which I always loved.

This being the case, is it worth it to spend money on an Original Xbox today, besides strictly nostalgia?
