@Dakota6060,

Welcome to our HP Community forum!

The HP Omen 35L is a prebuilt gaming PC with a proprietary case and motherboard layout. Whilst it is designed to accommodate upgrades, it does not natively support standard ATX gaming motherboards due to the following factors:

1. Motherboard Size and Mounting

• The Omen 35L uses a custom motherboard, and its case often has proprietary mounting points and dimensions that may not align with standard ATX gaming motherboards.

2. Power Supply and Cable Management

• The power supply cables are designed for the existing layout and may not reach the connectors on a standard ATX motherboard without extensions or modifications.
• The case may also have proprietary connectors (e.g., front panel connections), which could make installation tricky.

3. Front I/O Connections

• The front I/O (USB ports, audio, power button) may use proprietary wiring that is incompatible with a standard ATX motherboard.

4. Cooling and Spacing

• The case’s cooling setup (fan placement, airflow) might not align with a larger ATX board, leading to space and thermal issues.

 

Options If You Want to Upgrade:

1. Micro-ATX Motherboard: Some users have reported success with installing micro-ATX boards in similar HP cases. These boards are smaller and may fit better, though compatibility issues could still arise.

2. Modding the Case: If you're determined to use the Omen 35L case, you may need to drill new mounting holes, use adapter cables, and modify the case.

3. New Case: The easiest solution is to purchase a new standard ATX-compatible case to ensure compatibility with your chosen motherboard and other components.

If you're considering an upgrade, confirm dimensions and compatibility of your intended components before proceeding.

Let me know if you'd like help selecting compatible parts!
