I know the guy is trying to save money, but for the love of god do NOT tell him to cheap out on the power supply. It's literally the most important component in a computer, as a crap PSU can and will fry the entire system. PSU's that come bundled with cases are always built as cheaply as possible in order to keep the price of the case down, and this one is so ludicrously underbuilt it's a fire hazard - I mean, just look at these reviews:While I couldn't find any professional reviews of this particular model, I did find one for the 450W model: http://www.hardwaresecrets.com/article/Apevia-Turbolink-ATX-TL450W-BK-Power-Supply-Review/1212/1
In short, don't buy that combo unless your parents have a good home insurance. There's a Corsair CS450M for $50 /w rebates if you're interested: http://pcpartpicker.com/part/corsair-power-supply-cs450m
Oh and don't tell him to buy ECS, either; they have had a reputation for building cheap and unstable motherboards for at least a decade. MSI may not be the best manufactuer out there, but they're not THIS bad.
You're probably right about the psu. The positive reviews far outweigh the negative ones, but for a $700 build a nicer psu is definitely doable. However, I disagree with you about MSI vs ECS motherboards. ECS builds cheap motherboards, not unstable ones. MSI builds more premium motherboards, and they
are unstable. There have been numerous bios issues in the past year or so I've seen when populating all of the ram slots causes BSOD's, constant crashing during driver setup, and other issues. The actual board may be manufactured with better components, but that doesn't mean anything if you can't use the board. From what I've seen MSI has sub-par customer service, with a lot of RMA's taking forever to complete or not at all. ECS seems to have pretty good customer service, and there haven't been many DOA boards at all.
If you think ECS isn't that great of a brand I don't fault you, but MSI is worse imo. There are cheap H81 gigabyte boards to be had, if you don't want ECS I would go with those.
