So the title is self explanatory. I dont like how most M-ATX cases look and want an ATX one but dont know if it will fit properly. Motherboard is an MSI A68HM-E33 V2
Choose your preferred case, then check it's specs sheet on the manufacturer's website - - it will show which motherboard form-factors it supports. Most cases designed for ATX boards will also be compatible with micro-ATX ones, but easily confirmed as I have suggested above.
