I'm thinking of buying a Western Digital Caviar SE16 WD5000AAKS 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive - OEM. OEM is my operative word. I operate with Windows Vista Home Premium. I have never bought OEM equipment. Will I be able to install this hard drive into the open bay on my Gateway FX530S without additional equipment such as a case, cables, etc.? I believe I have, or can download, the needed software. Thanks in advance for any assistance you can provide. Happy New Year all.
