https://www.techpowerup.com/303226/in-win-mod-free-takes-case-modularity-to-the-nth-level Over the past decade, PC cases have grown increasingly compartmentalized, but rarely modular. A case could be partitioned horizontally, or vertically to accommodate the various purpose-built chambers, but why should you stick to a particular pre-set arrangement of the compartments? In Win has an answer to this question with Mod Free. This case can either be a tall full-tower, or a horizontal stack of compartments, depending on how you want it. You can reconfigure the case as many times are you like, to grow with your hardware upgrades. The detachable modules can even hold secondary ITX-based machines, entire DIY liquid-cooling setups, large arrays of storage devices, or dedicated to graphics cards. Reconfigure and reshape the case as you like.
I really like this idea. Lots of flexibility to make the PC case in the size and dimensions you want.
