This is a self-built server, ready to use once you install an OS. Each part is a high-end, carefully selected, and quiet design. The CPU has 12 cores and 24 threads, and with 256GB of memory, it may be suitable for virtualization platforms or AI. It also has many SATA connectors, making it ideal for storage with HDDs. It was used as a node in a VMware vSphere cluster until recently. It is being sold because the equipment was replaced. The original case was reused, so it will be shipped in a new case. === M/B...

None The accessories are all shown in the photos. The Windows screenshot is for operational verification and does not include a license. The firmware has been updated to the latest version, and the IPMI settings have been reset to factory defaults. The IP address is assigned via DHCP, and the login username is `ADMIN` with the password `ADMIN`. Please note that the temperature of the memory modules tends to rise, especially under high load. Although I have not experienced any problems using it, including ECC error correction, please be careful not to lower the fan speed too much, which can be set from IPMI. Alternatively, you may want to add a case fan. If an error occurs, try turning off the power and restarting.
