Look for a serial ata to parallel ata interface adapter.
A well made adapter can cost anywhere from $25 to
$35 and they do take up some space on the back of
the drive.
If this is in regard to the newegg mistake, if I was you
I would set aside the sata drive until you get a mobo
with the sata connector and buy another 80Gb pata
drive for a few dollars more. I personally dont think
the adaptors at the prices I saw were a better idea over
buy a drive that connects right up. Just MO.............
