looking for an external HDD (hard drive) to build. so need to buy the case and the HDD separately. looking at building a external HDD that is compatible with firewire and USB 2.0 but the internal connection needs to be SATA as i can not find an IDE HDD with 750gb, not that id want to. that tech is in the past. so far the best i've been able to find is a case that is SATA connected but only has USB and eSATA external connections. pleas post links cherz.
