Does this case have USB 3 on the front io ports ?

Yeah it has 2 USB 3 ports, An audio input and output jack and a reboot button (obviously an on/off button as well haha)

Would the Corsair Hydro H100 x 240 fit in this case??

Yes it does, I have fitted my Corsair Hydro H100i Platinum RGB on the top. There is plenty of room. You should have zero stress putting an AIO in there.

What size are the fans?

It has 3 fans, not one like the other person said. The description and images clearly say it has one at rhe rear and two on thw front panel. They are all 120mm

Does the case have room to comfortable mount a 3.5" HDD?

yes there is, in the back if you attach the included rubber feet then it is easy to attach a HDD and there is also room for 2 2.5mm HDD or SSD
