Until it’s recent morph into the Xeon Tube, the Pro certainly was the most PC-like Mac, in its reluctant pandering to people who needed things like ‘expansion cards’ and ‘multiple hard drives’; but the comparison between the cheese-grater Pro (PPC or Intel) and contemporary single and dual socket workstations from other vendors is still aesthetically pretty brutal.
Compare, say, the timeless beauty of the Dell Precision 490 dual-Xeon workstation (mid 2006)
With the internals of the G5 and Xeon based Mac Pro equivalents:
The P490 works just fine; but the wiring would shame your average gamer slap-together job, despite Dell having essentially arbitrary ability to get bits and pieces built to suit, in volume.
This “Ives” Leica is basically gluing the cheese-grater faceplate to the P490 and calling it a day.
