I dont think anything is necessary, other than upgrading your storage. I considered an SD card, and decided the price break was just better overall for an ssd. I got a western digital 512 for like 55 bucks I think.
The hardest part of the swap was getting the case apart. I did watch a couple of videos for tips before I did it though… it made it pretty painless. the biggest pro tip was to start the separation of the case by one of the trigger buttons, and just run a credit card along it to pop the tabs. Another suggestion is if you dont have a set of tiny screwdrivers, i would recommend getting a cheapo kit. I had one I made due with, but even it was slightly too big for the task.
Like I said, I would watch a couple of vids so you know what to do as you proceed, how to flash the new ssd with the os, etc. It really isnt that hard. I am not too terribly of a tech savvy person and was able to do it.
I just got the bottom dollar deck, and it came with a case btw. I bought a cheap dock off of Aliexpress and it works fine. I think I paid under $25 for it… i am certain you could probably get the same one on amazon for ~the same price. I definitely wouldnt buy the valve dock. If you dont have a controller, the world is your oyster. I bought a cheapo $30 bitdo.
I think the brand of screen protector I bought was Ivoler, and it was a very easy install… it came with a “frame” to square the glass install.
Good luck, i have been enjoying mine.
Its nuts that during the Obama admin, all anyone cared about was the threat of zero privacy. Now everyone in the US has surrendered to it, because our politicians have sold our digital privacy rights to the tech companies.
