Right, but that also means sourcing a grouphead, a suitable boiler and all the other bits. Plus worrying about thermal cutout, running the boiler dry, OPVs, all sorts of safety things. Having someone else handle that is nice. Those projects also exist, but the point is you can buy a platform that has all of that in a nice chassis and only need to replace the control system by mitm-ing the wiring.

It looks like a cool project for sure https://www.diypresso.com and actually reasonably priced for what you get and what a similar spec system would cost off the shelf.
