$210 · Alienware 17 (2014) with PROBLEMS -- price dropped

I have an alienware 17 bought in 2014 (cost more than $3000). It comes with: Intel core i7-4910mq CPU Nvidia gtx 880m 16gb ram 1tb hdd However, it comes with few problems: 1) the discret gpu is NOT DETECTED. which means, I weren't able to use it for heavy gaming anymore. I can only load from integrated graphic (Intel HD 4600) 2) there is a dent on the upper left corner of the keyboard and TAB key is kind of loose, but they are all in working order. 3) the plastic shell that covers two hinges is broken. It is still working okay. Other than that, this is still a functioning laptop. You can still do web browsing, work/school, and even light gaming on it. I have installed windows 10 pro on it.
