In my experience the weak point here is the controller/firmware. We bought a bunch of high-endurance Enterprise MLC drives (also Intel but newer) and one of them has already bricked itself, way before reaching any kind of wear worth mentioning.
Good point! Unless we have a EMP! ;)
Edit: I found my M2 spacers I ordered by mistake 5 years ago, they are a bit wide at 18mm but that is good for thermals! Genious!
Edit2: Ordered 6mm spacers! You can get an idea how it will look here: http://move.rupy.se/file/SSD_unit.png
More important than cooling is the voltage rails. Reliable PSUs that don't overvolt the load under any scenario are important.
Will use Mean Well from 220V -> 12V... but after that it's PicoPSUs! (160/180/200W I will try many to see how their 3.3/5/12 look, I think this drive uses 5V but how can I find out? also measuring voltages on a live circuit has burned me before how do you make sure not to short/fry stuff?!)
