Easier Building: Tools like Velcro straps, hinged side panels, modular drive cages, and integrated fan hubs are becoming commonplace.

Vertical Integration: Cases are increasingly designed with specific cooling solutions (AIO radiator placement) and GPU sizes in mind.

Aesthetic Refinement: The shift is towards clean aesthetics, integrated RGB lighting (not tacky), and premium materials like tempered glass and brushed aluminum.
