purchased 2years ago but never loved it. the back side have cable issue when i have to add sata ssd and HDD but the major issue i faced recently is using second GPU using b660m mortar motherboard. the gpu holder also not reach to the gpu.
the CH370 was designed to have top AIO cooler with fan but what about the second GPU, the second GPU not fit and need extra 1cm of space. 
my top side is blank because i am using air cooler and no fan at the top but no space to add dual slot gpu. the cabinet PSU container have extra space but there is no way to remove or adjust height.
it is frustrating now need to move to ATX case for a m-atx motherboard. avoid this case just in case if you want a peace of mind.
