1) Ignore the word, "Extreme" in the system's name. "Extreme" it is not!

From an off the shelf stand point, it looks fine. From a builder's stand point, it looks like a nightmare. Unknown power supply. I'm guessing that since it's an XClio case, it's probably an XClio power supply. Which one, however, I have no idea. Not the best choice in power supplies regardless.
The motherboard is an ASRock H61M-HVS. Still running SATA II/USB 2.0. The specs on Newegg (taken from IBuyPower) state Gigabit Ethernet, but the motherboard specs only state 10/100 Ethernet. Only one PCI-Ex16 (used) and PCI-Ex1 expansion slot on the Micro-ATX motherboard, but installed in a case that accepts full ATX motherboards.
To me, while the entire system seems functional and able to do what your daughter wants it to do, to me (as a builder) it seems more "cobbled together from spare parts" or "skimmed down to bare essentials", than a well designed system.
