A little backstory + a technical question (not related to the question in the title):
So yeah, I built my brother a computer with an old MSI MS9803 and a Core 2 Duo t9300 some time ago, and while the motherboard had been acting up for some time, it worked fine. Well, until we moved it to his new desk, and had to cut power completely. While I wasn't included in this process, I have no reason to believe my mother could've fucked something up. It would refuse to boot - as in, nothing happens when you push the button, short the pins - whatever. I checked the CMOS battery, and, sure enough, it was pretty much empty. I bought a new one, and put it in. This didn't help, so I'm pretty clueless as to what the problem could be. If someone has solved a similar problem, please respond. I have no reason to believe that the PSU should be at fault.
Actual thread material:
My brother needs new parts. I've been thinking of getting either an i3 2100 or a Pentium G820, as HT is pretty much the only difference, with a Intel H61 mATX of some sort. This is a 10-year old, mind you, so nothing with excessive power is needed. I've got a GPU and PSU for it, a 4830 and pretty reliable 430W. I don't need a case, OD or HDD, OS or whatever periphial you might encounter on your quest for computer parts. As I am pretty knowledgable with computer parts, my real questions is really for alternatives. I've been out of the rubby business of PC building for some time, so I'm not completely hooked on the competition.
Just for reference, here's the parts I planned on buying (you can use the site for searching, as well):
