I think having the door of a case hold the motherboard and components is probably outdated as it not as feasible as it was back then. Look at how big GPUs are taking 3, sometimes 4 slotswish someone would just flat out copy that design internally
Personally while that was an intriguing design, I have found other cases to be better in both looks and cabling management. Personally I love pre-trash can Mac Pro design. Now that is clean and wonderfully laid out - both the intel and PPC versions.
