If you haven't heard of it, have a play with PC Part Picker. Making something like this for your site would be really interesting IMO.

This is really really cool. I've worked on similar systems of bundling together parts, and your site is well-executed. Maybe you could call it "Pricewatch for Drones"?

This is great! I was thinking about building my own drone, but was having trouble finding a starting point.

Do you mind to share what stack are you using to build it?
