M920q vs OptiPlex 7070 Micro
The two most common used home-server boxes: which should you buy? The differences that matter for a home server:
- M920q can take a PCIe card (PCIe x8 via riser); OptiPlex 7070 Micro cannot. Choose M920q for a router, 10GbE or an HBA.
- M920q has a built-in path to a second network port (PCIe x8 card via Lenovo riser (replaces the 2.5" bay)); on OptiPlex 7070 Micro you would need a USB adapter.
- The top CPU option in M920q has 12 threads versus 8 in OptiPlex 7070 Micro.
- M920q has a path to 10GbE networking; OptiPlex 7070 Micro is limited to 1 GbE plus USB adapters.
