Non-standard power supply connectors make standard case or PSU swaps extremely difficult.
The HP BIOS (Phoenix-Award) is notoriously locked. You cannot overclock via FSB adjustments. You cannot adjust memory timings manually. The CPU microcode is limited to HP-qualified processors. Upgrading the CPU often requires a BIOS update that HP no longer provides on their website (use The Retro Web or Vogons archives). Yes, the HP 8653 motherboard has an M
The primary storage mechanism relies on a single M.2 PCIe NVMe slot. Upgrading to a high-speed PCIe Gen 3 or Gen 4 NVMe SSD will vastly improve boot times and application loading speeds.
For many users, the HP 8653 is perfectly adequate. But for DIY enthusiasts, its lack of standard connectors and upgrade path might be frustrating.
