Why does it have to be low-spec? I bought my current laptop with 16GB of RAM in it (soldered to the mainboard, sadly) because that's the most the manufacturer offered at the time. If I had the option today, I'd open it up and swap out the modules for 32GB. (I think they now offer a 32GB model.)

Ditto for the storage; I have 512GB in there now (probably wasn't the max when I bought it, but seemed sufficient and was a good price trade off), but I wouldn't mind swapping it out for a 1TB part. Actually, this bit might be possible to do myself; I should look into it.
