Taking a look at the inside, it is set up for the PATA hard drives, as we figured seeing as all of the SATA parts were outside. Since I will be using a Seagate SATA drive (w/o NCQ), I will need to switch everything out.
The power plug is easily switchable from the 4 pin molex to the flat SATA power molex. Taking the front panel off was easy and then the side with the company logo slides out to open up the inside.
I also removed the 40 pin PATA cable to keep the inside nice and clean. To be able to add the drive without taking everything apart, they have the side panels come off to open up the holes to screw in the drive. This makes installing a drive very simple and quick.
