If you're waiting for a steam deck to be available i have good news. The problem was that they used all of the locktite in the world on one of the screws on my steamdeck which made changing the ssd a PITA on mine, i ended up destroying that screw. I'm sure they'll get more locktite abd begin shipping to you soon. I use arch btw.
7/8 came out with no problem, that's still pretty good. I ended up using a tiny flathead to get it out but that joker was too far gone to go back in. Next i might try that clear back with improved passive cooling. I figure if the fans aren't working so hard the battery might last a bit longer.
