Hi!

I am looking for a case with the following requirements:
1) 4 PCIe expansion slots (thus the mATX requirement).
2) Allows for video cards at least 310mm long.
3) Will take a standard PSU (Corsair RM550x).
4) Is the smallest possible format that fits the above...

Max CPU cooler size? Doesn't matter. Ventilation? Doesn't really matter. Amount of drives? Doesn't matter. Price? Not really an object (but let's say under 200$ to have a semi-sane upper limit).

So far it seems like the Silverston SST-SG10B is the smallest this gets. Does anyone know of any smaller cases that still fit these requirements?

The In Win 301 handles cards up to 330mm, has 4 PCIe slots, fits standard Power Supplies and is rather compact at 14.3" x 7.4" x 14.6".

Best of luck with whatever you choose...:),

are we measuring in liters or dimensions? a cube & a 90 degree gfx card flat case may end up with the same total dimensions, but wildly different height or width

We are sort of measuring in both volume and linear dimensions, so keep the suggestions coming, please.

The In Win 301C looks very promising as well, thanks Liquid Cool!

I believe the In Win 301C was just released? For the price point, it seems like you're getting quite a bit of bang for the buck.

Since the Fractal Design cases are popular here at TPU, I was originally going to suggest the Fractal Design Mini C TG, but the dimensions were a little larger than the In Win 301. 15.7" x 8.3" x 15.7".

Again...best of luck.
