I need to sell my PC ASAP. Where can I do it?

Hello

Me and my gf need money urgently(dont ask why) and we were thinking of selling her pc. As I said, its urgent, basically for tomorrow, but we have no idea how or where we can sell it or sell its parts. So I have some questions I would love to ask for anyone who has experience with this?

- Where's the best place to sell PCs or PC parts?

- Are pawn shops a good option? Heard they are basically scammers?

- How long would it take to sell it on Facebook's marketplace?

- What should we avoid when selling a PC or it's parts.

- Is it more profitable to sell the whole PC or it's parts?
