This old IDE drive might greatly slow down your new system
Its true that it might slow it down but if you have enough RAM, that wont be a problem at all. I have 2 IDE HDD and my pc runs perfectly with 2GB DDR2 RAM memory. For the power connectors, you will need a compatible power supply like the Dynex® - 400-Watt ATX CPU Power Supply . It connects IDE and SATA . http://www.bestbuy.com/site/olspage.jsp?skuId=8311052&st=power+supply&type=product&id=1174091945952
