Jethro - thanks for the reply and welcome. I wont have many inputs and questions, but do need an outlet when I get frustrated:bow:
Unfortunately, from what I can tell, I cannot remove that ATA connector any other way except via the large hammer method which is not conducive to part longevity. It looks like, after doing some more research the Dell has done "their thing" and made an almost proprietary ATA connection to the back of the existing DVD-ROM which is on the opposite side of what I believe to be the industry standard. Now, with the additional connectors inside the bay will work with another type/brand other then a SunTek or OEM Sony, I would give that a try - but without sure knowledge that would work, can't justify ordering a 'trial' piece.
As a note, these proprietary Dell 'designs', after having a couple of early motherboard deaths are one of the reasons that I tend build my own PC type desktop computers (laptops - they are still a mystery)
