I got this
https://www.amazon.com/dp/B01M7V19JE
and threw a couple dozen in my foam case, a few in my ammo box, and then found other stuff around the house to use the rest on. They have beads that change color when saturated, and you can microwave them to ‘recharge’ them.
I used these. I like them because they change colors when they’re completely saturated with moisture
skip the freezer/fridge whatever little moisture that is in the powder will end up hydrating again when you take it out to thaw...
transfer the contents out of whatever baggie you have and find a nice jar that can be airtight... like a mason jar... use desiccant link below and if you want you can vacuum seal the jar and just keep it out of the light

The pelican desiccant quickly becomes a moisture sink and the metal case can come apart. Tape them together if necessary. Also, who has time to microwave/oven any their silica packs?
I use these. They change color when saturated and need replacing. With cases I only pull out a few times a year (RZ Kit) I throw a new one in every time.
I would use silica desiccant packs instead. I use Wisedry Silica Packs with the color change.
Oxygen absorbers are for long term storage (multiple years), and don't necessarily do that great at keeping things bone dry. The way oxygen absorbers work is by rusting iron filings in the presence of oxygen and humidity. If there's no oxygen, but there's still humidity, the reaction will not work, and you'll continue to have humidity in the container.
Silica packs are good at keeping things dry, but don't absorb oxygen, so only good for shorter periods depending on humidity (so less than a year or two).
If you can't empty the #10 container fast enough, pour it into bell jars and add a desiccant pack. If you have a food saver with a bell jar attachment, you can also vacuum seal the bell jar. Depending on the food, I would still include a desiccant pack. I've had freeze dried apples go soft (not crispy like usual) in the vacuum after being packaged on a humid day.
I got these: https://www.amazon.com/Wisedry-Rechargeable-Desiccant-Indicating-Reusable/dp/B01M7V19JE/ref=mp_s_a_1_9?crid=3JFHLBE8FD2S2&keywords=wisedry&qid=1647117791&sprefix=wisedry%2Caps%2C145&sr=8-9 They have larger packets as well, but 5 grams doesn’t take much space and seems good for jars up to a liter or so.
Rice is bad. There are fine pieces of it that get in everything and will cause excess corrosion inside.
Get some dessicant packs (like THIS instead).
5 Gram [60 Packs] Silica Gel Desiccant Packets with Orange Beads Humidity Indicator Safe Double Packed for Air Dryer Moisture Removal, Food Grade https://www.amazon.com/dp/B01M7V19JE/ref=cm_sw_r_cp_api_glt_i_WYX0PYBH52G9YBKM8634
Are these safe for card storage? Says food grade.
You could speed up the drying process by placing your computer inside of an airtight (doesn’t have to be perfect) container with a desiccant.
You can find this stuff at most department stores, in various packaging, but often for moisture removal from damp spaces. Here is one on Amazon, but you can definitely find this locally so you can get to drying out your computer ASAP!
You could also increase airflow near the computer, with a small fan or the like, to enhance the evaporation of the water from the laptop.
Some folks here are suggesting rice, which is also capable of absorbing water. It can be dusty and include small or broken grains, that can become lodged under keys and within small ports/fan grilles, etc. if you do utilize rice, just be mindful that you don’t create another issue by getting it where it shouldn’t be.
Best of luck to you, be sure to let this dry out before powering it up (you might consider removing the battery if it’s possible), as this can create shorts on the chips within your laptop that can damage individual chips or potentially disable the computer as a whole.
I would just buy those card boxes you mentioned in the OP and limit how much you shift things around, it is not the boxes that are causing the scuffling as much as it's just the cards rubbing together.
I also bought these silicon moisture packs and put them in the boxes to reduce moisture the cards take in which cuts down on risk of having the cards warp
If it's under warranty try to get a replacement.
However I highly recommend anyone with these amazing headphones to get Silica Gel Desiccant Packets with Humidity Indicators https://www.amazon.com/gp/product/B01M7V19JE and every night put these headphones in a sealed bag after wiping it from sweat of course with the desiccants (2 in each earpad) to help it dry and prevent issues like this. I did this after noticing the noise-cancelling feature would start to do crackling noises after a few hours of wearing them and being slightly sweaty. Bonus: it helps reduce any smell and increases durability a lot, considering these headphones aren't sweatproof.
My old headphones (MX2) would do something similar to this with different third party earpads if they were close enough to eachother, in that case cleaning the areas where the microphones are with a tiny bit of alcohol and gentle brush can help too.
WiseDry makes "rechargeable" food grade ones in different sizes. For folks new to food storage, keep in mind that moisture packets are different from oxygen absorbers.
