I installed the 4TB version in a small form factor Dell PC (dell optiplex 7050 sff). The slot was not big enough, but made it work by installing this hdd on the top slot so there was some room till the top of the case. So my hdd is sticking out of the slot by a bit. I am not sure how the 2.5 inch bays of the InWin Chopin look like, be sure to check for the size first!

I think so.
