I could, yes. The laptop has an M.2 slot that is intented to be used for M.2 SSDs, maybe you know them, they've gotten very popular. Almost any mordern motherboard has space for them.
But instead of putting an M.2 SSD in that slot, I bought this adapter with SATA ports. And this adapter fits exactly in the same spot as the SSD could have. Then the SATA ports of the adapter can just be used as regular SATA ports as on any motherboard.
I thought about replacing the entire bottom part of the laptop, but then I looked at the screw layout and thought this is way too much effort for not much benefit. I am not lacking in rack space so I am okay with it being bulky.
If you don't mind the price, the Prusa Core One checks all these boxes. It is what I have and use happily, with PLA, PETG and TPU.
I bought the assembly kit, and it was built within a weekend following the very good assembly manual. But you can also get it pre-assembled.
Material wise you can consider PETG, it gives me nice durable prints on my Core One.
The HDDs have their own 12V 10A PSU.
