I know there are already posts about this, but none of them answer my question precisely. I have a Lenovo Y700 34-ISH Gaming Desktop. My specs are: Intel Core i7 6700, Nvidia GTX 970, 16GB RAM 2133, 2TB HDD. I would like to find out if my motherboard is ATX or mini ATX WITHOUT opening the case. I went on my CPU-Z onto motherboard tab, and it says my motherboard model is the Lenovo Skybay 40709 WIN 32595860. Thanks in advance!
