I wasn't allowed to build my first PC due to "trust concerns". Instead, we ordered from a pre-built system manufacturer (Digital Storm) costing us a ****load of money and not allowing me to learn the skill of PC assembly. I have since pretty much gutted my tower, but it still stands that some parents may not trust their children's judgement and instead (if they have the money of course) purchase the most expensive model, believing it to be the "best" for their child's needs.
