I am looking at an Antec sp500 for my Dell dimension 4500(it was a repo from irresponsible son # 2) This Dell is actually a standard atx form board. It seems to me that Dell ps are way overpriced particularly when they are not proprietal rewired versions. The sp500 has the fan on the right side and the power plug is located correctly as well. All I will have to do is cut a litle hole for the on/of switch. What I am confused about is the 4 Sata connections this PS has. I need to connect a video card, two optical drives and four IDE hard drives with the older style 4 pin plugins. It has a spare molex connector according to the specs but I am not sure what that is. Will this ps work for me?
