No, you meant 2.5" ...

You can't plug it into a PC, it's different to a 3.5" IDE connector.

You might be able to plug it into a laptop, if you're OK with taking the laptop apart.

I'm assuming it gets its power from the IDE cable?

Aye, power delivery is part of the connector itself...

But I couldn't get my IDE cable to fit in it... They seem to be spaced slightly differently or something.

...via the 44 pin connector that comes with tighter spacing than the 40pin IDE connector.

Am I a retard? How do I plug the drive into my PC? Or don't I?

I can't answer that definitively but I can say that you were just under-informed. There are 2 ways to get it right now: externally via an adapter/cable device that lets you jack the nekkid drive in via USB or in a suitable (laptop)IDE-equipped external casing; or inside the machine via a 40/44 adapter that bridges the two different form factors.
