For a system using a single GeForce GTX 560 graphics card NVIDIA specifies a minimum of a 450 Watt or greater power supply that has a combined +12 Volt continuous current rating of 24 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.
The Corsair Builder Series CX430 V2 (CMPSU-430CXV2), with its combined +12 Volt continuous current rating of 28 Amps and with one (6+2)-pin PCI Express supplementary power connector, is electrically sufficient to power your system configuration with a single GeForce GTX 560 but is deficient by one 6-pin PCI Express supplementary power connector so you'll have to resort to using a dual 4-pin Molex peripheral to 6-pin PCI-E power adapter cable.
In Hardware Secrets' review of the Corsair Builder Series CX430 V2 (CMPSU-430CXV2) they were able to draw 36 Amps from its +12V rail.
That PSU has only one PCIe power connector, so you'd have to get an adaptor just like with the CX430. It can theoretically deliver a tiny bit more power than the CX430, but it's much less efficient under load and just generally not a good quality PSU.
Cooler Master make good CPU coolers and computer cases, but their PSUs are hit and miss at best.
Looks good on most counts. I don't know the case and there don't seem to be many reviews around. It's probably fine though. As for the CPU, I think you can get a core i3-2120 for just a couple dollars more. It's only a small upgrade, but easily worth a few dollars.
