You two are acting like the plane has to be a zero factor in order for the sabotage to occur. What happens if you attack a beam that is already suffering some measure of heat stress?
The two competing theories are:
1) - The plane impact, together with burning combustibles, brought down the tower.
2) - The plane impact, together with burning combustibles, brought down the tower with the added help of some thermite/thermate.
There's no need to discuss straw man option #3:
3) - The plane impact and burning combustibles played absolutely no role whatsoever (perfect zero) in the collapse of the building. Saboteurs rigged it up in a separate, and independent way that didn't involve the plane, or impact at all.

There's nothing suspicious about a company loading up a bunch of new computer hardware into a building over the summer and then waiting to turn it on until several months have passed. That sort of thing happens all the time in big business. Sometimes the whole project gets scrapped and the machines just get carried back out of the building, having never been turned on the whole time they were there.
The point is that it wouldn't be hard for someone who knew the schedule to use the batteries as a way to smuggle in large amounts of something dangerous, confident that building security wouldn't go disassembling expensive computer equipment just to make sure there isn't a bomb in there.
But, the thing is, they'd be tested after being moved in. They most definitely would be turned on, at least once, to ensure that the massive server room they'd be supplying wouldn't fail in the first day or so of operation.
And, as you said, it isn't suspicious to have a room full of UPS's, because they have a purpose and are often necessary. It's highly, HIGHLY, unlikely that someone with intimate knowledge of the building's scheduled installations would be a part of a conspiracy to bring down the WTC, and just adds an additional assumption to be made by conspiracy theorists.
That is a good point. It depends on a lot of things. Maybe their IT department was busy on another project, so they just had a moving crew bring everything up and leave it. Maybe the electricians weren't done wiring the floor to be able to deliver power for that many machines.
I also agree with you pointing out that Al Qaeda could have introduced the batteries them self using a well placed operative.
