Does someone know how to adjust or edit your HDD cage? I've already looked inside my rig,
but the only thing i see there are like those unscrewable screws. With only a dent in them (circle depression hole thing)
Some people say to drill them out, but is'nt there any other way to adjust my antec 300 for my upcoming HD5970?
Nope. I have the same case. If I wanted to upgrade to a 5970, I would cut out the part of the cage I don't need to make room. That would cut out maybe 3 of the 6 top spaces for HDDs. So if you don't mind being limited to 3 HDDs in your case then it's all good.
