I have an old computer case that's almost the same size of the Blackhawk Ultra case. The only problem it that it's ugly and doesn't have enough places for fans. So I've been working on modding it for a future build that I will get around to building some day. (I'm a major procrastinator)
Anyway, on the Blackhawk Ultra case, it has these screw hole thingys for screwing fans in. Here are some pictures of what I'm talking about
I didn't circle the holes in the below picture:
Does anybody know what those are called? I can't really do a google search and buy them if i don't know what they are called lol. Googling "screw hole thingy" or similar stuff hasn't really helped.
