Questions about this item

Does the Gigabyte C301 GLASS case include a monitor or do I need to supply my own display?

The PC is a desktop tower only; you must provide a monitor, keyboard and mouse to use it.

Will my existing 2.5G Ethernet switch work with the motherboard's 2.5G Ethernet port?

Yes, the onboard 2.5G Ethernet port is backward compatible with slower switches and will negotiate the highest common speed.

How can I verify the 240mm liquid cooler is keeping the Core Ultra 7 265KF at safe temperatures?

Open the RGB-lit glass panel, check that the pump and fans are spinning, then monitor CPU temperatures in Windows Task Manager or a hardware utility while gaming.
