I really like this case, but that is a lot of money. My P180, which I'm currently still using, was ~$180 new. Not sure if I want to upgrade, but if I did I would give this a serious look if it is ~$200.
"Inside the enclosure there is space for three 3.5" drives."
curious that the picture shows either 4 or 5 drives installed.
More curious that the antec web site specifies nine 3.5" or 2.5" drives.
You need to open your eyes.
Also it makes no sense for a premium case to only support 3 drives.
So you aren't looking at your own pictures, or applying common sense.
