My case can fit the Ventus OG GPU but i couldtn find it anywhere in my country, And ordering it onnlinne would take weeks.So basically you need RTX 2070 with length 200mm or below.
Only single fan ITX versions will satisfy that requirement:
MSI GeForce RTX 2070 AERO ITX 8GGigabyte GeForce RTX™ 2070 MINI ITX 8GBTW - MSI GeForce RTX 2070 VENTUS 8G OC - is 226mm long. Doesn't fit your requirements.
