[SOLVED] First time installing case fans, need help

[Lance_Lionroar]

Hello. PC noob here. A few months ago I bought a new rig which had a cheap case: Gigabyte C200 Glass. This case comes with one exhaust fan and no intakes. I looked into it now as we're approaching summer, and decided to buy 3 120mm fans which the case supports in the front.

Here's my problem, I'm too bad at putting things together and have no idea how to install it. I can't find the case manual either.

Here's a picture of the fan with the screw. It doesn't screw all the way into the hole, it just kinda gets stuck so I'm not sure what to do.

And a picture of the front of the case. I assumed those elongated grooves/openings are where the fans fit, but as I mentioned I can't get the screw to go all the way through the fan screwing holes and into those grooves.

Any help is appreciated.

Also, I've been thinking I probably need to do it from the opposite end, but that requires removing the front of my case and I don't know how to do it.

You put the fan inside the case and you screw the fan from the outside.

Take the front cover of the case off to gain access to the front side.
Find the corresponding slots with the fan holes and insert the screw through the front side into the fan on the back side then screw in.
