What do you think about these components for my first built PC?

First off, ditch that PSU. Diablotek is a horribly-cheap, OEM manufacturer, and their power supplies are utter garbage and fail every time. Putting that thing in a computer would be a liability and firecracker at any given time. You seriously need to stick to reputable, QUALITY brands, such as Corsair, SeaSonic, Antec, XFX, PC Power & Cooling, Thermaltake, Silverstone, Cooler Master, or OCZ. Stick to a power supply from any of those brands, period. Everything else looks decent. You didn't include a video card, so I take it you don't plan on gaming? Yeah, don't plan on any gaming on integrated motherboard graphics, either.
