Looking for advice on what Gaming Laptop I should buy.

So I haven't bought a new laptop in years, and with tomorrow being Cybermonday I am really interested in buying a new gaming one, so I thought to ask here for some recommendations. There a few notes though:

-My budget is $1000 and below.

-I have a lot of files, so I care about its storage being upgradable, including it having a place for an internal HDD inside it not just an SSD (It doesn't have to include large storage from the outset though, as I intend to upgrade it. It doesn't even have to have any internal HDD installed, just include the space for one)

-I care about its build quality and durability not just its specs. I take my laptop with me to many places, and I once had an Asus that would get some issue with it every couple months after a year or so. By contrast, my Dell laptops have generally been pretty durable, so I generally prefer Dell products as a result, but I am ok with any laptop brand as long as it is generally considered durable and has good build quality.

-I am not interested in a touch screen. I don't mind it, but it isn't a plus for me.

Sorry for the many notes, but I wanted to explain my preferences well. And thanks in advance :).

Also, any recommendations for large sizes SSDs and HDDs on sale? Both to add to the laptop and as external storage.
