Well the #raspberryPi M.2 hat is installed & it's booting from a 1Tb NVMe drive.
It's a lot less fiddly than the base units I have & there's clearance so it doesn't affect the active cooler.
That said it's a tight fit for the official case & the screws it comes with are too short for the case so you need longer screws to secure it completely.
Also the top is very tight & without those screws it's easy to accidentally remove the hat by accident when powered up if it's used.
