Nice to have full enclosure! When you run full coolant and decent toolpaths, you get stuff everywhere.

There is also a Taiwanese VMC on ebay similar price, possibly better quality and condition, less well known.

You would run these off a VFD. Usually only the spindle needs 3 phase and you can run the coolant off single phase with a motor run cap to create the 3rd phase. The other stuff in the cabinet can usually be rewired for single phase without too much buggerage. And if you need to restrict the max power draw, you can change the VFD parameters or worst case get another VFD where you can do that. If you are drawing 10HP you will be shifting some serious swarf, so dialling it back to a few kW won't be a big issue.
