Does the Gigabyte LGA1151 Intel Z170 ATX DDR4 Motherboards GA-Z170X-UD3 fit in the corsair spec alpha case? And also I have a pavilion http://support.hp.com/us-en/document/c02174835 will all the components without the motherboard fit in this case? I already bought the gigabyte and it didn't fit in the stock case so I don't want to return it to amazon and wait for the money return, so I thought it would be easier to get a new case because I wanted one anyway.
