A:AnswerThis is probably too late, but I would suggest opening it and reseating all the parts and connections that you can (e.g., that connect to the MOBO). It could be a RAM or power issue, but it more than likely is the GPU.
A:AnswerThe HP OMEN 16L comes with a 1TB NVMe M.2 SSD that's a 2280 size drive that fits into a PCIe 4.0 slot, uses 3.3V DC and 2.5A, offering up to 6000 MB/s read speed and up to 5400 MB/s write speed. It does not come with a camera.
A:AnswerI imagine that both could be upgraded. The CPU would need to fit into an LGA 1700 CPU socket. And although you could upgrade the GPU, you might have to also upgrade the 500-watt power supply to support the new GPU.
A:AnswerUsually on these pre-builds, they put whatever appropriate MOBO they can get at the time of assembly, so I doubt you will get a single, final answer.
A:AnswerI believe so, especially since you mentioned open-air. The main concern would be any obstructions to its air vents. I recommend contacting HP and asking them directly before deciding to do this, though.
