Is the ST45 V3 good for a small office?

Yes. It handles file sharing, print services, a small database and light virtualization for a handful of users. It is not built for heavy compute or large virtual machine counts.

How much memory can it take?

Up to 64 GB of DDR5 ECC memory. That is enough for a small office but well below the hundreds of gigabytes rack servers accept.

Does it come with an operating system?

No. Lenovo ships it without an OS, so you install Windows Server, a Linux distribution or a hypervisor yourself.

How does it compare with a rack server?

It is quieter and needs no rack, but it has fewer drive bays, one socket and PCIe 3.0 slots. Choose it when space and noise matter more than density.

What security features does it have?

It includes a TPM, a power-on password and an administrator password. These protect the boot process and BIOS access.

It is a tower with a 300 W supply, so it runs quieter than most 1U rack servers. It is not fanless, so place it where some airflow noise is acceptable.

Our take on the Lenovo ThinkSystem ST45 V3 7DH51003NA Tower Server

The ThinkSystem ST45 V3 is a single-socket tower server built on an AMD EPYC 4004 Series processor, aimed at small businesses, branch offices and schools that need a real server without a rack. It takes up to 64 GB of DDR5 ECC memory, has PCIe 3.0 expansion slots and dual Gigabit Ethernet, and runs on a modest 300 W power supply. Compared with rack servers it is quieter and easier to place, but it offers fewer drive bays and less memory capacity than 1U or 2U rivals. It suits file sharing, light virtualization and line-of-business apps rather than heavy compute.
