M720q vs OptiPlex 3080 Micro
PCIe riser or newer 10th-gen CPU? The differences that matter for a home server:
- M720q can take a PCIe card (PCIe x8 via riser); OptiPlex 3080 Micro cannot. Choose M720q for a router, 10GbE or an HBA.
- M720q has a built-in path to a second network port (PCIe x8 card via Lenovo riser (replaces the 2.5" bay)); on OptiPlex 3080 Micro you would need a USB adapter.
- OptiPlex 3080 Micro officially supports 64 GB of RAM versus 32 GB, useful if you plan several VMs.
- Onboard Ethernet differs: M720q uses Intel I219-V, OptiPlex 3080 Micro uses Realtek RTL8111HSD.
