Is the HP Z2 Tower G1i good for CAD and 3D work?

Yes, with the right configuration. The Core Ultra 9 285K and 32 GB of DDR5 handle CAD, BIM and rendering prep well. Check that your configuration includes a discrete GPU if your software relies on one, since many ship with integrated graphics.

Can I upgrade the memory and storage later?

Yes. The tower has accessible DIMM slots and drive bays, so you can add RAM and a second SSD without special tools. Confirm the exact slot count and free bays for your configuration before buying.

Does it support Linux?

HP lists Linux-ready configurations, and the Core Ultra platform has broad kernel support. Check HP's certified Linux list for your specific model and distribution before relying on it for production.

How does it compare with a Dell Precision or Lenovo ThinkStation tower?

All three are single-socket professional towers with ISV certifications. The Z2 G1i stands out for Thunderbolt 4 and easy chassis access; Dell and Lenovo offer comparable CPU options and their own management tools. Choose based on the GPU and warranty your software vendor supports.

What comes in the box?

The tower, power cord and documentation. A monitor, keyboard and mouse are not included unless your configuration bundles them, so plan for peripherals.
