Ductwork doesn't have to be below the floor. Modern co-lo facilities that I
have been in (such as Switch Supernap) don't have a raised floor.

Plumbing (unless you're doing aisle containment or RDHx) shouldn't run
through the IT space in the data center.

Cooling water to racks should be dewpoint adjusted, so you don't need
condensate drains inside the DC.

And overhead trays are much more difficult to

I solved that by having multiple ladders. In my experience, it's a lot
easier than trying to reach through a cluttered raised floor under racks.

The only good reason that I have seen in this thread for a raised floor is
to match older equipment that routes cables downwards.
