I don't suspect that everyday PC's are listed as information technology equipment. UL has special listings for IT equipment.
I think you will be as surprised as I was when read what that includes.
From the 2010 UL General directory.

Interconnecting cable assemblies: Cable assemblies intended for use
beneath raised floors of computer rooms. These assemblies are also covered
under Computer Interconnection Cable Assemblies (DVPJ).
Included within the above groupings is equipment which is battery powered,
either by standard-size consumer-replaceable batteries (e.g., AA, C, D),
or nonstandard sizes specified by manufacturer, type and ratings.
This category also covers power distribution units (PDUs) and computer
power centers investigated as part of a computer system for use exclusively
in information technology equipment (computer) rooms in accordance with
Article 645 of the NEC. This equipment is connected to branch circuits
unless otherwise indicated in the manufacturer’s installation instructions,
and it distributes power to other units in the computer system by means of
interconnecting cable assemblies complying with one or more of the wiring
methods outlined in Article 645 of the NEC. Many of these units require
special installation, such as a separate transformer, special grounding methods,
motor-generator equipment, air conditioning, etc. Such features are covered
in the manufacturer’s installation instructions
