Looks like you are off to a good start. So the first thing you need is a compatible Motherboard. Obviously it's an Intel and it's an 1155 socket. Also you need a board that has 4 dimm slot's for your memory. Most do unless you are doing a micro atx or mini itx build. Are you familiar with newegg? They don't ship internationally but have a huge selection and an easy to use website that can help get some idea's. Tigerdirect does ship internationally.
Your cpu, ram and videocard are all compatible with those boards. Might be a good place to start.
As far as a power supply I would strongly recommend making an investment in this department, not a place to cut corner's.
A modular power supply will make a huge difference and possibly save you some frustration with not having so many excess wires.
Here are a few high quality psu's ranging from less than 100 to about 200:
I would suggest getting at least 100w more than what is recommended for your video card, cpu etc.
