you're in luck! the motherboard in your computer is a microATX one, but that case also supports microATX. Remember, when swapping the motherboard, make sure that you label/make a list of where all the small cables for the front stuff goes (powers switch, hdd light etc.).
also, make sure that your current power supply unit will fit. if the computer is a 'small form factor one', it may not.
(from what it says, a new psu comes with the case)
