In Win is always a stand-out attraction at PC trade-shows, and at the 2023 International CES, they presented a vision for what PC cases could ship like in the near-future. PC cases, particularly $20-50 ones, are incredibly uneconomical to ship, as they take up vast amount of spatial volume for the market-price. The new In Win POC isn't exactly an entry-level case, but adds a heavy DIY element to it, similar to what you'd find with Ikea furniture.

The In Win POC case comes in completely knocked down kits, with nearly all its metal panels flattened. There are cutouts on the panel, along which you manually bend and fold the sheet-metal to construct 3D shapes, as shown in online instructional videos made by In Win. A few bends and tightening of joints later, your case is ready for the hardware to be installed. The knocked-down case comes in an incredibly compact box that's a fraction of the volume of what would've been for a factory-assembled case, and needs much less protective Styrofoam. The concept carries on to the Dubili, a rather upmarket-looking ATX mid-tower which, although doesn't come with "fold here" sheet-metal, remains in a completely knocked-down state out of the box, with mostly flat bits that you join using a series of thumb-screw joints to give the case its 3-dimensional form.
 
This could be the future of low cost and high cost PC cases where you assemble the cases yourself. 
 

I would be careful because sheet metal can be very sharp on the edge which is why most nice cases fold over the metal at the edges. First cases I built I remember always scraping up my hands every time I worked on them.
