In addition, two SSDs and WLAN modules can be installed in two M.2 slots – but only one at a time. Other drives fit two SATA-3 sockets. If an SSD is installed in the M.2 slot, however, one of the SATA sockets can not be used according to the manufacturer, as the ports share the bandwidth.

Many ports and passively cooled

There are also ports on the side: two USB 3.2 Gen 1 ports, four USB 2.0 ports and two RJ45 ports for Gigabit Ethernet. Screens are optionally connected to VGA or HDMI.
