Before you go spending money, you need to make sure that your existing case will allow for a different motherboard. Many name brand manufacturers have proprietary/custom mounting holes so you may not just be able to drop in a new something. I am not familiar with Acer, so it may be ok, but you may want to consult with the store where you bought it as far as what your system will allow to be replaced as well as if you will be able to re-use your existing Windows license or have to buy a new OS.
