nier-automata
In NieR:Automata, you equip chips to your memory, which improve you in some way, whether it be through HUD enhancements or attack/defense buffs.
However, I noticed that you start the game with less than what seems to be half of the maximum capacity. I'd originally assumed that leveling up increased your storage, but it doesn't appear to work that way, since I'm now Level 11 and have unlocked no more storage.
What do I need to do in order to unlock more storage capacity?
Skins are listed as Key Items. Once you've redeemed the preorder codes for the skins, they will appear in your Key Items and you can simply equip them from there.
From this guide:
First off, bring up the game’s main menu and head over to the Items tab. Look for the Key Items option and select that. Here, you’ll find all the important items you’ve picked up over the course of the game. Select the skin that you want to equip, and then hit the Equip option. Once you do this, your Pod will assume the appearance of whatever you picked for it.
While I don't have the time limit for when your corpse will actually disappear, I can confirm that the time limit is longer than two and a half hours, as that's how long I waited. Two hours and 39 minutes, to be exact. Unfortunately, I had to go somewhere, which means I had to put my PS4 into sleep mode (which may or may not affect this timer, so I'd need to start the test over if I want to try again).
During my testing, I also ran to another section of the game, then fast-traveled back to near where my corpse was. The corpse was still right where I'd died, so distance and fast-traveling don't seem to affect the corpse, either.
In general, though, the purpose of my asking this question was to gauge the sense of urgency (if it existed) to get back to my corpse in time before it disappears. Apparently when the tutorial says "an extended period of time", it damn well meant it. As such, it seems like if you have any desire to recover the chips you lost when you died, there is no chance you will run out of time to do so.
If I ever have an entire day to kill, I may attempt this again to see if I can find the exact time limit. Until then, just know that the time limit is absurdly generous.

As with many things in the game, this is a mechanic that isn't really explained to you. According to the wiki, there is a Maintenance Shop on the Bunker that will sell you chip storage upgrades. An alternative is the female android in the Resistance Camp who sells Pod Programs. She also sells the storage upgrades. Buying from one seller will cause the other seller to no longer have it in stock, though, so you can't double-dip.
The shop appears to sell 2 +8 storage upgrades for 5,000G each, an additional 2 +8 storage upgrades for 10,000G each, then 2 +16 storage upgrades for 20,000G each, and finally, a single +32 storage upgrade for 30,000G.
Combined with the starting storage of 32, you can have a maximum of 128 storage space for chips.
