I recommend you sit on this idea for a month or two. If you still feel just as excited and committed to it by then, it might be something you take seriously.
In this moment, the idea of getting rid of your PC equipment might seem exciting, because you're really interested in something new. The problem is that your enthusiasm and excitement won't necessarily last very long. Once you sell up and get the FPV quadcopter, you might find it isn't as interesting now that it is a reality, and you will feel regret.
I speak from experience. In my teens, I routinely convinced myself it was a good idea to sell my laptop, my phone, my gaming consoles, or anything of value, to put into something new. I'd make up all these reasons in my head to try and justify selling things I shouldn't have. I often regretted doing it, and in the end I had to get a job to replace some of the things I had lost. It felt good when I was caught up in the hype of the moment, but once I bought whatever it is I wanted, I would get bored with it and end up selling it on.
Last year I bought a KORG LP-380-73 digital piano. I had been wanting a digital piano for about 5 years. I was finally in a position where I had saved enough and could buy one. However, I'm not cash rich, so there is always somewhere more practical the money could have gone, and I knew it was a lot to spend at once. Because I had waited to do this for half a decade with unwavering enthusiasm, I knew that it would be money well spent. As it happens, it has been one of the most satisfying and fulfilling purchases I've ever made. What is the point of this? There is a difference between what you think you want now, and what you will enjoy in the long term.
I'll find some videos and upload them later. Don't worry about getting rid of everything, just keep what matters.
