There's a possible problem. Most newer mtrbds. provide only 1 IDE(legacy) port, so having 3 IDE devices may not be so readily installed. Why, because SATA is the primary access ports. If you want to keep the 3rd IDE device then either add an IDE adapter/card to access such. However, it maybe better to go full SATA, instead. If you find a dual IDE port mtrbd. its probably an older model, so take that into consideration. Just check the specs that Asus provides on such details via the support website.
