The HP FXM1 / E93839 is a compact, soldered-CPU motherboard built for entry-level HP All-in-One PCs. It supports DDR4 SO-DIMMs, one SATA drive, and optionally one M.2 SSD (SATA preferred). It cannot be used outside its original AIO chassis without heavy modification, and its CPU is not upgradeable. Focus upgrades on RAM and replacing the HDD with an SSD for noticeable speed gains.
If you have the exact AIO model number (e.g., HP 24-f0028), I can give you CPU and BIOS specifics for your variant.
Look at the lower half of the board. You will see one PCIe x1 slot and two standard PCI slots.
The PCIe x1 slot was for modern peripherals (like a Wi-Fi card). But the PCI slots are the veterans. These were used for specialized hardware: fax/modem cards for dial-up backups, firewire cards for video cameras, or professional audio recording interfaces. These slots tell us that this motherboard was a tool for professionals, not just consumers.
With these upgrades, the HP FXN1 E93839 can still run Windows 11 (with bypass), office suites, 1080p video, and esports titles like League of Legends or CS:GO comfortably.
However, for modern AAA gaming or video editing, this platform is obsolete. The LGA 1150 socket reached end-of-life in 2015. If you are building from scratch, look for used Ryzen or 8th-gen Intel systems instead.
