The awe induced when standing in front of a brand new, kitted out x95 frame with all its drawers full and that special shade of IBM blue on everything is definitely something. Pull out the HMC and just think about how many decades of R&D and experience and tears went into the entire system.

I think the driving force behind the look of the recent mainframes is from IBM's Italian designer, Camillo Sassano:

Well there's a whole group, but Camillo is the guy I worked with when I was there.
