Hi madblam

I would say no. As it's already quite a small case, you have to make some compromises :)
I have installed a 90x90mm fan in the bottom of the case, where it would also be possible to install a 2.5-inch HDD (but only if you use custom mod cables or if you are brave enough to shorten all the excessively long cables yourself. As it is just under the PSU.
I have also seen some with a 2.5-inch HDD installed on the front behind the cover.

There is some sort of space for a very slim SDD HD under the case(you even have 4 holes for the screws). The only issue is the space for the cables, you have to be very skilled to route the cables as the internal space is too tight. Better check some videos on how to build a pc with this case
