so i have an unused PC with no case, it has an i5 4th gen, ECS 1150 motherboard, 4x2gb ddr3 and zotac gtx 750ti . and i found someone who sells dell optiplex cases for cheap, it is around $5 if its in usd. the thing is will my mATX motherboard and its other component fit to the case? i got this idea from a youtuber who build a gaming pc using dell optiplex and it seems like a good idea lol.
