Newbbuilder11's post clearly illustrates the "almost" you can run into when buying a prebuilt. That PC would no doubt perform better than the laptop. It might actually make a "tolerable" starter system. It has three obvious deficiencies, however, which would need to be addressed.
1) Most trivial, its 8GB of RAM is a single stick. The faster (3%-5%) dual-channel mode requires two identical sticks.
2) Most serious, its "350W" Allied PSU-shaped object may be unfit for purpose. Likely capable of 200W-250W (which is enough for this system), it no doubt lacks good filters and protection circuits, meaning it may die for unknown causes (e.g. Mom turns on the vacuum cleaner on the same circuit), and may take other parts with it. It is particularly important to address this issue before...
3) The GT730 is a barely entry-level card for games. It may be fine for games like Minecraft, but if he wants to play shooters, will likely be woefully inadequate. The included PSU-shaped object will not support an upgrade to this.
Incidentally, unlike what the description says, the Pentium is NOT a quad core CPU. It has two cores, and is not hyperthreaded. Fine for many games (especially since it is overclocked; the motherboard choice looks good in this system), it will struggle in newer ones, and any that are well-threaded.
