Only low profile video card may fit in DT case (unless you take off case side panel and let full height card stick partially outside case).  Mini video card typically means short length card with only one fan.  max card length to fit 7010 DT is about the width of OEM motherboard in that case. [IMAGE]          
I have a Dell optiplex 7010 DT will a Nvidia GTX 1050 Mini fit in my PC.
Will it fit?
