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.
