Dell Inspiron 530 no drives detected

I've had this Dell sitting around collecting dust for a while, and I recently decided to do something with it. I had an OS X Mavericks install app on an external drive, so I decided to use it with the system, because I have a newer Mac now that doesn't support Mavericks. I ran through the Unibeast setup and formatted my flash drive, then put it in the computer to have only the flash drive appear in Disk Utility. I am a noob with this stuff, so I need some help with a detailed guide to fix the issue. This computer doesn't have AHCI mode, it only has IDE and RAID mode. I tested both modes and it still didn't recognize the drive. Thanks!

Updated, but it will change. I plan on picking up a Core 2 Quad Q9650 and GTX 750TI in the future. I just want to focus on getting the drives formatted and OS X installed right now, then I'll worry about the smaller things.
