I saved almost $200 by getting the 64GB model and installing an OEM 512GB SSD myself versus buying the 512GB model. (I didn’t buy an iFixit kit or any other fancy stuff, since I already owned an electronics repair driver set, and I got a USB-C dock back when I got my Steam Deck and was already using it regularly outside of needing to install SteamOS on the new drive.) The “hassle” was largely nonexistent - the biggest problem I had in the whole process was needing to discharge the battery before getting to work, which I did by…playing games, on a game system.
