It sounds like the cost of trailer and gas, not including your time, will be high. It would have to be for love rather than seeing a "value" in restoration and sale. That's my guess.
But restoration of something can be so much fun and a Case tractor isn't a bad thing to do up. The fun and satisfaction should be worth it as it isn't going to blow the average budget.
If you have some use for it, that would be handy. But even if it is a trophy for the shed or yard art, they look great!
