The Node 202 is pretty old but still one of the best flat SFF cases out there, since i repurposed my old Sapphire Nitro+ Radeon RX 580 recently in this case, i needed a custom fan duct

most models out there did not fit or were plain wrong, so i built my own by starting with a small frame template of the Node 202 you can find as a separate download

The Duct is intended to be short, since the cooler is a hybrid “blower” that pushes out air through the backpanel and the front of the card coaxial to the PCIe connector, the right side is open, for exhaust

mounting is done with 4 standard 5 mm screws for PC fans

temps are better than without a duct, but still are on the hotter side - so don't forget to rise the feet or use the case upright
