RX570 isnt going to work because its UEFI card.and the stock power supply isn't big enough aka 500W or more.   Newer than Pascal for Nvidia will have the same issue. Older cards if they are not 12 inches long aka 6 to 8 max will work if they are single slot cards. So any card like the Zotac Mini series works if you have enough power supply. only nvidia GT1030 GDDR5 is viable if you do not update power supply.

I am building a sleeper gaming pc with the dell Inspiron 531 fat model case. I know it’s a micro atx case but since the hard drive cages are in a weird spot I want to know if it’s possible to put an rx 570 gpu in it
