No. Typically, the IT person is not doing their own tech work in an office setting, due to the bureaucratic nonsense of accountability, ticket sign-off, and things of that nature. That there is only one person in the cube, and that it is clearly their assigned cube, and that they are not working on another user's system, directly invokes that this is not an IT person.
But again, she DOES get props for being geeky enough to know how to hotwire the ATX power supply.
Generally speaking, the gender of the person does not trigger me, it is the behavioral archetype that triggers me. "bubbly airhead" is not limited to blonde secretaries with nail files. There are plenty of airheaded guys in offices, who cant figure out how to use the printer. If you are a bubbly moron, you set off my competency alarm. If you set off my competency alarm, I am going to WTF if you even so much as look like you are picking up a screwdriver. Male or female. If however, you are confident, and show basic competencies, I will give benefit of the doubt. In the case of this lady, I did not question that she knew what she was doing, as far as disassembling her workstation -- She was doing it correctly. I was just wondering "why is she doing it?", as in "Is there something wrong with it? It seemed to be operating fine---" with the secondary thought of "This looks like her own workstation, why did she not file a ticket instead?... That clearly cannot be kosher in her company..." then "WTF!? why is she washing the door?!" which then became "OPEN FLAMES!? WTF!!!" etc.
