I was thinking the same thing when I got my A7V133. I cannot put the CD Burner or DVD drive in 5.25 bay 3 and 4 as some capacitors are in the drives path to make it flush on the outside of a mid tower case. I did not have this problem with the CUV4X I had previously. Now I am thinking of getting a full tower, maybe the HX08, on my next rig.
