Listing includes

* Asus Prime Z490-A motherboard (originally bought from Newegg on 7/2021)

* Intel Core i9-11900K (originally bought from Amazon on 8/2022, system was upgraded)

As a bonus I will include the Noctua NH-D15 Cooler (with one fan) that was installed in the system; see pictures.

CPU will ship mounted in the motherboard (safer that way, to protect the motherboard CPU socket), the cooler and fan will be unmounted and wrapped separately.

The parts where taken from a working server which is being upgraded.  The server was used headless as a file server and continuous integration machine for about 2 years.  Never overclocked.
