I wouldn't suspect you would need to upgrade anything in that for 5+ years. The only thing to add might be more RAM, which assuming the 32GB you have in the cart is 2 16GB sticks won't be a problem as you could pick up 2 more sticks at any time down the road assuming you can find the same model. Or worst case buy 64gb and just sell the 32gb you have.
Realistically the only things you'd swap out is a better/more modern CPU down the road which would require a different Motherboard anyway, or a better/more modern GPU which are very interchangeable as well.
