You will have to pull the ram from the factory out where you can sell it to offset the cost but they you will have to buy 4 16gb sodimms. This won’t be cheap as current pricing seems to be about $1000, but it’s doable.

If you’re in the market for a cheap computer to use for back to school, this Lenovo Thinkpad X230 is a pretty good deal at $125.00.
