I notice a fair amount of case fans in near proximity. Intake or exhaust? LOLOLOLOLOLOL

This case is a little weird on the bottom it has two Intake fans the AIO is Intake and the top two fans are exhaust and two on the back Exhaust. The case mod isn't permanent and I had to reshape the boards.

Highly doubt that large of styrofoam is going to dislodge and suck into a case fan. No harm intended or implied judgement being passed on your mod.
I'd bet 100% of people responding today have done similar things in the not so distant past.

Bought a cheap Xiaomi IEM and it sounded like it's price, disgusting. It sounded hollow and to make matter worse there is this gain (very coarse sound throughout the spectrum, like you have a bad cough). At work today I noticed there is two holes on it like pictured below

So I tried to plug the hole, so I summon the tape, this is the tape that you used on the floor (you know the hazard black/yellow striped one, THAT ONE).

Plugging the top hole corrected the coarse sound but it makes the very narrow soundstage even narrower. So what about the bottom hole?

This makes the soundstage wider and tighten up the bass so it didn't sound hollow. I like it but the grainy sound is back. So I try plugging both holes, the result? It sounded clean and sound like any generic IEM, strong bass and narrow soundstage. That is with black tape, how about other tape? I summon masking tape next

With masking tape in place the bass isn't as strong as the black tape and sounded rather nice actually, from what I observed the inside the Sennheiser HD555 really looks like it was put with masking tape (you can Google for HD 555 driver and see what I mean). But I don't like how it looks. So one more tape, this time is teflon tape

It sounded better than the black tape but slightly worse than masking tape. Eh I can live with that. This turns from 1/10 in sound quality to about 5/10, it still sucks for some serious listening but not too bad and actually passable for casual listening besides noisy machines at work.

You might try sticking them in a pillow or somewhere that maintains sound pressure similar to your ears and let them play at a reasonably high volume while you are work for a full week. Part of this could easily be very stiff cheap drivers needing to break in.

Holes appear to be for venting heat if that helps you get closer to understanding the efficiency level they were designed to meet. My guess is you will notice them getting quite warm.

When you have an old laptop with no keyboard but you want to protect its guts from dust, cardboard comes to help.

I use it as a media player when I lay on my sofa if I don't want to use the TV.

I don't believe in break in, but it didn't hurt to break in this one so I'll try thanks.

It didn't heat up or anything at all so I believe it for bass port for product placement to make it sound worse (I bet this have the same driver as the higher end model but maybe worse in QC I dunno)

You need to upgrade to greasy pizza box cardboard.

The greasy side downwards?

makes for better thermo-electric heat conductivity*.....

I left it overnight playing all sort of music at two ticks above my listening volume while I put it on sponge with laptop brick holding them and I be damned. Today I removed the top hole and the graininess is gone! I hear it sounded better too some of the fuzzy background details is clearer now. Guess they didn't run them down just check they produce sound and onto the box it go.
