> You then need liquid cooling connection As far as I can tell, they don’t need external water connections. While everything serious is liquid cooled, they have on-rack radiators. The z17 machines are shipped with the cooling circuit sealed, so it doesn’t need to be filled before use. Power consumption is also relatively low because that’s one demand their clients have that they don’t expand much on top of z16. They are very power-efficient machines. My only complaint is that there’s no desktop or desk side version. Using z/OS as a daily driver would be an interesting challenge.
