Bizman, that mobo won't handle the cpu you picked.
How come? ECS has the G3430 on their list:

For the RAM, I simply chose the cheapest and for what I know, Kingston is a well known brand. I agree, for a gaming rig a z87 would've been a better choice, but this built was meant to be a cheap but decent family computer for banking and youtube with some expanding possibilities for photo editing (max 32 gb ram) and light gaming. Since the purpose of this project is to teach kids how to build a computer and then sell the results, IMO the biggest potential clientele would be the parents whose kids force them to buy their precious work. The cheaper the better in this case.
