Lappy to PC conversion questions

[caoxite]

Hi, I’m planning to remove the motherboard from my HP Pavilion x360 14-dy0050TU and mount it in a custom external case because the stock chassis and fan assembly got damaged, and even when it was intact the laptop used to run excessively hot. Instead of repairing the original housing, I’m exploring whether it’s realistically feasible to run the board outside the stock enclosure, potentially mounted inside an ATX case, and what limitations I might face regarding power delivery, BIOS/firmware restrictions, proprietary connectors, and fan/heatsink detection. I’m also considering integrating a Peltier (thermoelectric) cooling setup with the existing heatsink for maximum cooling, and possibly connecting an external GPU (via M.2/PCIe adapter or similar), so I’d like to know if the board’s power limits, PCIe lane availability, thermal sensors, or VRM design would cause major issues, and how serious risks like condensation, VRM overheating, or firmware lockouts would be. Any insights or experiences from people who’ve attempted laptop motherboard conversions, ATX transplants, or eGPU setups would be greatly appreciated.

Hi @caoxite,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

Sorry for the inconvenience caused don’t worry let me help you.

I understand how concerning it must be to deal with overheating and chassis damage on your HP Pavilion x360 14‑dy0050TU. It’s clear you’ve put a lot of thought into alternative solutions, and I truly appreciate the level of detail you’ve shared. 

Perhaps HP designs its motherboards and cooling systems to work specifically within the original chassis, and moving the board into a custom case or using non‑standard cooling methods can introduce risks overheating, or firmware incompatibility.
