checkerboard

Hi! Some time ago I got this used GPU, the guy I bought said it was from a office but almost sure it was from a mining rig. After some time using it I got the pattern like that in the image down (it's not a screenshot from my pc, is from a post on this forum but it is exactly the same pattern)...

which looks like this,Checkerboard Artifacts. This PC im using is New about 2weeks, all parts are new except the GPU which is an Sapphire Nitro+ RX480, This GPU was used in 2 Previous builds and worked flawlessly! here are the specs of the PC. PC PartPicker * Keep in mind this error happens...

Hi, I have a mini ITX case but am strugling with storage. I had 3 large HDDs in my old build and would like to connect them to this system. Is there a smart way to do that? one that does not include holes and velcro on the outside of the case... Thanks
