I use a Proxmox cluster in my production environment.
I would like to utilize CEPH or LINSTOR to ensure my data is redundant and to easily migrate VMs between the nodes.
I noticed that a 1Gbit connection was not fast enough to support the VMs, so I started researching the issue.
Soon enough, I discovered that the EliteDesk 750 G4 had an extra M.2 A+E slot where the WiFi module was installed. Since I don’t use WiFi for a Proxmox cluster, I ordered the following network card 3 times:

To neatly mount the NIC in the chassis, I printed the following mount:

The NIC is fully supported in Proxmox, and I am now able to sync the LINSTOR/CEPH storage over a 2.5Gbit connection.
Unfortunately, the chassis didn’t close properly, so I had to remove the following part to ensure the top closes neatly.
