On that topic: MFF PC territory - was originally looking for a cheaper clone of the Jonsbo D30 (the Gamemax Spark is only available on Amazon Germany AND its now 10 - 20 Euro more expensive than the original!), but stumbled upon a cube case called
Mars Computing MC-400 (available in black and white), with a dual-chamber design, with optional 240 mm rad fitting in said second chamber. Its roughly 29.87L (30.4 x 27.6 x 35.6), so a bit bigger than the Jonsbo D30, but smaller as eg. the Asus Prime AP201.
My guess is, when using a smaller ATX or just a classic SFX PSU, that even an Artic LF II might fit (depth of the second chamber should be, based on the pictures, approx
90 mm).
There are still the parts of my old computer sitting around, so it might be a good option for my planned "hodgepodge" build, ie. after thoroughly cleaning everything, because its ultra-dusty, despite havin been only seen use for about 2 1/2 years. That build would include at least a GTX 1660 deshroud with replacing thermal pads and paste, but if I got the rest working again (AMD Ryzen 7 3700X, MSI mATX B450 board, 16 GB RAM, etc.), I'd be more than happy to give this case a try
