I like building up computers. Its fun planning out the parts lists and choosing exactly the components you want. Assembly is really fairly simple and there are a lot of guides out there. Its the software installation and troubleshooting that can be the most frustrating if things go wrong. I say go for it if you have any interest. You can enjoy picking exactly the case, the fans, the lighting, the CPU cooler,... its all custom and you built it. If you do explore this, I'd recommend pcpartpicker.com to help with picking compatible components.
