All the manufacturing engineers I've talked to hate doing fluid dispense. Glue is in a class all its own because if you take the line down it tends to cure in the dispenser or nozzle.

Fluids/moltens are a nightmare.

The PS4 officially supports replacing the internal hard drive, and that's not even getting into the question of repairs

If I could have one change to electronics manufacturing, it would be a ban on glue for non-waterproof devices. Most repair-hostile trend in history.

I took apart my PS4 Pro several times since I own it. It’s very easy to do, nothing is glued, and the plastic clips that hold the cover in place don’t break when you unsnap and snap them back.

The only thing is an obnoxious warranty void sticker that delaminates if you don’t lift it carefully but even then I don’t think it’s legal to void the warranty with a sticker (Switzerland, bought from a EU retailer)

You can get replacement stickers for around $10 on eBay. Sadly the PS4 line looks a lot better with the stickers on as they hide exposed screws.
