Hello, I'm kind of disappointed by layouts of SFF up there lately. For long time I'm having idea of a new (but not very revolutionary) concept I didn't seen anywhere. Closest to this idea is Raijintek Metis. Metis case however has lots of compromises and cannot support high-end gaming system without overheating (IMHO). So I downloaded couple of free 3D models and sit for a while at SketchUp (is this a correct tool for prototyping?). Main features of this concept: - one full length GPU up to 3+ slot wide - tower CPU cooler up to 160mm height - 160mm ATX power supply - no PCIe riser cable - 2x 3.5" HDD (system disk is a M.2 drive) My aim is to have small PC case that support classic GPU/CPU+cooler layout. Center of the idea is optimizing of the airflow in the case. I stop talking, here are the concept images: PSU should be take fresh air from the front (Raijintek Metis missed this so horribly) CPU on the other hand will breathe through sidepanel GPU takes air from top: There is lots of place for full-length GPU with 3-slot cooler (Palit GTX 1080 GameRock anyone?) and 160mm long PSU with modular connection. Two 3.5" HDDs can be installed. Case can be optimized for ITX as well. Really rough dimension measuring shows 350 x 200 x 285mm => 20l Some more images: I would like to see your opinions on this. I would even be more happy to see somebody to grab sketchup 6 file and finish my poor design in proper 3D model.
