Not sure about the case but the power supply may be somewhat lacking and a cx430 is not going to make the grade, either. A 500 watt PSU is required for the video card, with 1 X 75 Watt 6-pin PCI Express power connector is required.
■Certified power supplies are recommended. Please refer to:

I'd suggest a 650 watt minimum PSU however should you upgrade in the future, you will also have to upgrade the PSU to match your hardware. The total power input of all of your hardware combined should equate to 80 % of the total power of the PSU so that you are not running at peak power all of the time and that there is a surplus of power should it be required.
If you are considering Windows 7 x4 or later then an i5 would better suit you, as well as the video card.
The video card is way too advanced for the i3 and you should consider a lesser model to suit the lesser motherboard. Also, the video card requires PCIe 3.0 and an i3 motherboard is not likely to have that feature so the video card will perform at a much lower rate, if at all.
