Ok you seem like you know your stuff, and im fairly hopeless just want to build a fairly decent computer for a good price. what i have so far is i want a Obsidian 650d case, a Intel Core i5-3570K cpu, and have now decided on the Gigabyte GA-Z77M-D3H, i want to have water cooling on it just to be safe and a Nvidia GTX 650 Ti Boost Graphics card, is this possible in this case and how many watt power supply do you recommend? I know there are other main components i need for this such as storage memory and optical drive but i think i can figure that bit out.
