The floppy drive bay depth thing finally clicked for me
Turns out those old 3.5 inch bays were keyed for the physical shroud of a floppy drive, not just any drive cage, so my 120mm radiator almost didn't fit my 1998 Antec case. I dug through a 2007 forum thread about the NEC FD1231H to measure the actual clearance at 41mm, and now I'm wondering how many of you have hit the same wall with AIO tubes in those front bays?
