Help with Broken Pc, can she be rebuilt and made better?

So my ex roommate threw my pc down the stairs(😞) and it’s not working..

I was wondering if the case is fine besides the front panel is it possible to rebuild?

Can I use this tower or should I get a new tower and build from there?

It won’t turn on at all so I know the power isn’t working or maybe it’s the motherboard? lol

I’m very very new to this. Also is there a way to tell what’s not working? I don’t want to waste anything. I purchased some ram and I can go into more detail or post more pics or whatever I need to do! I’ve never built a PC but I really miss my computer. Any help/tips/advice would be greatly!

Thanks 🙏
