My first build, not completely sure i know what im doing

[JamesAW_13]

This is my build so far. Will all these parts work together? I've been trying to read the specs and everything but when i asked on yahoo some guy told me the motherboard wouldn't fit the case because it's not micro atx. Its listed as micro atx tho. also, how do i choose a psu? and do i need to buy fans? sorry for the noob questions but i don't wanna spend the money and find out i screwed myself.
