I personally prefer building:
I don't have to deal with a preinstalled OS with tons of bloatware and can reinstall at any time if necessary.
I can pick all the parts myself, and I know exactly what's under the hood. No mystery motherboard; no propietary parts.
I can pick my own case and PSU: no wondering whether a new GPU will work with it or not.
No mistery or propietary drivers that are poorly supported
And of course, the pride and FUN involved in building it yourself. I love booting PCs for the first time...it feels like Xmas morning
