okay well you dont need a 600w PSU, try something like this:http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027
It will be $40 after rebate.
You could get a slightly cheaper optical drive, $17 instead of $23
But this only saves you a few dollars. When you have to buy an entire system AND a monitor it gets tough to do it for $650.
