- Does it come with the CPU installed?
- Yes. The Intel Atom C2550 is soldered to the board, so there is no separate CPU or cooler to buy.
- What memory does it take?
- DDR3 ECC SODIMMs, up to 64GB across the slots. Non-ECC may work but ECC is the point of this board.
- How many drives can I connect?
- Two SATA3 ports on board. For more drives you need an add-in controller in the single PCIe slot.
- What power supply does it need?
- A DC power adapter through the on-board jack, not a standard ATX supply. Check the required voltage and wattage before buying.
- Is it good for a pfSense firewall?
- Yes. The four Gigabit NICs and low power draw make it a common choice for pfSense and OPNsense builds.
- Can it run Proxmox or ESXi?
- Yes, owners run both. Keep in mind the C2550 limits how many busy virtual machines it can host.
