I've been putting together my first build and my case has made it am absolute nightmare(Antec 900) and I'm pretty much done other than I can't secure my video card to the case as there's no holes and the holes that are there you can't screw it to anything cause there's nothing under it just empty space. I also don't know what cables or whatever I need to be able to plug my drives to my motherboard. One of my system fans won't fit on but that's completely fine I just need some help with this video card and these drivers(cd drive, SSD, storage). Also any other tips of what to look out for because I'm not confident in my build because the case was so hard to work with and made things difficult so I dunno if I installed everything right but the card and drives are where I need to start. I have two cables I think that came with the motherboard but I have 3 things I need to plug in.
