What's the difference between a mid-tower and a full tower for a gaming build?

For a single-GPU gaming PC, a mid-tower is almost always sufficient and easier to live with. Full towers like the Define 7 XL are recommended by reviewers primarily for builds with many storage drives, E-ATX motherboards, custom water loops, or workstation/NAS duties. Specialist community threads frequently warn that full towers are overkill, and harder to position on a desk, for a typical gaming build.
