Modifying the network adapter for WD HDD

[RockBox]

I have several spare HDDs laying around, but they're all Western Digitals. I know that you can modify your network adapter so that a WD's extra jumper has room. I'd like to know how you can do it. From the looks of it, you just unscrew the metal plate, and then unscrew the chip that holds the EIDE interface, and plug in the HDD without the metal plate at all. Problem is, the EIDE is screwed down by these wierd little buggers...never seen screws like that. If anyone knows the correct way to modify a network adapter, or knows what I'm talking about with these screws (or is willing to pop open their own NA to see), I'd really like some help. It'd save me the $70 for a new hard drive.
