Our verdict
Open, repairable, and built to stay on the bench for years. The MK4S is for people who want ownership: open-source DNA, excellent documentation, and a parts ecosystem that assumes you will keep the machine a decade. It is not the cheapest path to speed, but it is the most reassuring. Overall 9.1/10.
Tom's Hardware's precision note on the MK4S is on the expert buying guide.
