If you're talking about Bitcoin mining, It won't be economically viable for you. But you can mine some altcoin which were designed to be mined on spare parts. I would suggest you to mine aragon2d or grin. It will be economical for you.
Why is talking about mining Bitcoin not economically feasible? whether the cost is very large or the way that is very difficult to do, and I want to know the reason why Bitcoin is still better than Altcoin like Aragon.
