motherboard fitting

hi this is probably a silly problem but i can't seem to fit my motherboard into my tower D:

the motherboard is an amd athlon x2 dual core ultra 6000+
the tower is an icute jet turbine atx pc case

is this a micro-atx motherboard? the instruction manual doesn't help me, and the case apparently didn't come with one what am i doing wrong!

thanks for your time

Can you be more specific how the motherboard does not fit?

What exact make and model motherboard is this that you have?

The motherboard manual should tell you what form factor that the board is.
