The HP FXN1 (part number E93839) is a custom motherboard designed exclusively for HP All-in-One 24/27-inch series released around 2018-2021. It is not a retail board; you will only find it inside pre-built HP AIO systems like the HP 24-f, 24-g, or 27-p series. hp fxn1 e93839 motherboard specs 2021
Key identification features:
CPU & Chipset: The FXN1 utilizes the Intel Q470 chipset, which is a step up from the consumer-grade B460 boards. The Q470 chipset supports Intel vPro technology, making this board ideal for corporate IT environments where remote management and security are priorities.

Memory: It uses SO-DIMM slots (laptop-style RAM) rather than standard DIMMs. This saves space but limits you to standard JEDEC speeds. While the board can handle 3200MHz RAM, it will often downclock to 2666MHz or 2933MHz depending on the specific CPU installed (i5 vs i7).
Storage: The board is modern in its approach, featuring a primary M.2 NVMe slot. It lacks native SATA data ports on the board itself, meaning traditional 2.5" SSDs or HDDs require a specific HP drive cage and cable kit that connects to the motherboard's SATA header (if populated) or USB header.
