Building a PC is great if you like the process, you already understand compatibility, and you have time when something will not power on. A lot of first-timers and parents do not want that weekend.
With a TrentCore machine, Windows is on and activated, drivers are sorted, it has been load tested, and there is someone local if it misbehaves. You still get a sensible setup. You skip the dead-on-arrival panic.
Want to build anyway? Fine. We will still advise, including when a ready system is the smarter spend.
