Question Will ESD from a vacuum cleaner damage the components inside an ungrounded/unplugged metal cased PC ?

The title says it all. Everywhere I look online its never one straight answer so hopefully I find it here cause I'm a little worried about whether or not my PC will fry itself.

The other day my mom had vacuumed the front and back mesh of my metal pc case. The entire computer was turned off and unplugged the night before due to a scheduled power cut. (I put ungrounded in the title because I assume when a pc is unplugged it becomes ungrounded.) I do not know if she actually touched the case with the plastic nozzle but for the sake of worst case scenario lets say she did.

As far as what I can find online, people have either said ESD damage from a vacuum is a myth or that its a ruthless killer. People have also said that components today are considered static resistant due to extra built in grounding features. I do not know if this is true as I've never heard of it before.

I'd also love to know if worst case scenario something did get damaged, what I could look out for to identify it.

Forgot to mention it is currently working right now.

In case anyone needs it, here are the specs of what I believe to be sensitive parts;
Motherboard - MSI B650 tomahawk WIFI
GPU - Asus TUF 4070 TI Super
Case - Lian Li LANCOOL II

"will it..."

Only way to actually know is power it up, see what happens.

It does currently work

Then don't worry, and proceed on with your day.

A plastic nozzle is generally safe and won't hold a charge. If it were a metal nozzle then you could worry.

As part of Type Approval testing, I used to zap the outer case of equipment with an 8,000V static gun. It sounds harsh, but we never had any failures. Charge tends to reside on the outside of a case, grounded or ungrounded.

generally the case it's self would be big enough to adsorb such a tiny bit of electrical potential, otherwise you unplug your PC, carry it to your car wearing a nylon top, and it would be dead

the more isolated an electrical component is the more at risk it is, because that same tiny bit of charge is bigger compared to the thing it is reacting with, hence even touching an delicate IC chip that's not mounted on a circuit board can damage it. That's why you use anti-static with PC components, but once it's all boxed up you can stop worrying about crackles from clothing
