Graphics card wont fit


Its a Coolermaster k380 + gtx 710
 


you have to remove the metal thingy that hold the metal thingies, remove one of those thingies that is in front of the pcie slot you want to use, then slide in your card and put back the metal thingy

which is as poorly detailed in the manual page 3 step 2.4
