Is a gifted gaming laptop worth refurbishing, or is this beyond help?

I want to preface this by saying I know very little about gaming laptops/computers. The laptop says it’s a: Dell Inspiron i7559-2512BLK 15.6 Inch FHD Laptop (6th Generation Intel Core i7, 8 GB RAM, 1 TB HDD + 8 GB SSD) NVIDIA Gaming GeForce GTX 960M, then has inside Crucial 8GB Single DDR3L 1600 MT/s (PC3L-12800) SODIMM 204-Pin Laptop

(Included entire title because I don’t know what the phrases mean lol).

I’ve been wanting to play a few games during downtime, so my friend gave me their old gaming laptop they don’t use anymore. While I’m thankful for the gift (donation is probably the better word), it’s in horrible condition. Some of the keys are missing, and the monitor lid is disconnected. The keyboard and base area is pretty separated, and there’s a random wire somewhere. Besides that, I believe everything is okay? I’ve only had it a few weeks and it runs well enough for what I need it for (just steam and bluestacks), and the only actual issue that I notice (albeit someone inexperienced) is aesthetic-wise/cleanliness (and most likely the shelf life of the computer, but once again I just am going off of knowledge of how it should “look”).

I play a couple hours a week (right now it’s just Fear and Hunger Termina) and don’t see it worthwhile to buy a new laptop with all points considered (broke college student lol). I attached some photos for context, and would appreciate comments/recommendations/advice. And I wanna reiterate that it was given to me this way, I had no part in the destruction of this poor machine. These pictures were also from before I cleaned it, but honestly I’m afraid to even go ‘crazy’ and de-sanitize it all because I don’t know what of this I can ‘touch’
