Depends on the graphics card. If you go for a GTX1650 I do recommend at least one case fan as intake to support GPU and PSU cooling. If you go for some lower TDP card you don't need additional case fans. I've also send a prototype to one of my customers who wants to try making a fan duct to cool a GTX1650 only with the front mounted Noctua.
Got my SMALL1 all sorted out today.
L12 GS1E with a hot rod top panel, cooling a 3600 paired with a 1650. The case is pretty impressive in terms of quality, coming from a Ghost S1 and a Velka 3. This thing is pretty sturdy and the anodization is high quality. Thermals are pretty good, but I also have a CPU cooler sticking out of the side of the case so maybe I'm cheating . Case came with any and all accessories one could need (SATA power cables, standoffs for A6 intake without turbulence, etc). I originally had an issue with my PSU and REVOCCASES was super helpful with getting it diagnosed and a replacement out to me.
Only real downside I see with this is the limited GPUs available in the LP form factor. The 1650 is pretty capable but I'm looking forward to a possible RDNA2 or Ampere or Lovelace LP GPU (hopefully with more than 4GB of VRAM too).
The 1650 is a little noisy on load, even after repasting, so I'm gonna get some Noctua A6 fans in here and start working on a 3D printed duct to cool the GPU directed when combined with a deshroud (maybe custom IO shield too? for better exhaust, sort of like a blower card).
