Fantastic customer service. USPS lost original package contacted Vilros and they immediately shipped out a replacement. Will buy again.

There's a line now present on the M2 Hat+ "about page" that someone has edited in: The M.2 HAT+ is only compatible with the Raspberry Pi Case for Raspberry Pi 5 if you remove the lid and the included fan. The same appears true for the Vilros RP5 case.

I already have the RP5 Active Cooler (SC1148) , and the Vilros RP5 case (VILP279). The tall spacers that come with the M.2 HAT are slightly too short to go over the cooler if you want to put the case cover back on. The stacking pin extensions are long and push through the M.2 HAT, but are also short enough that they don't push through to any usable length because the cooling fan is in the way, and even if they did, the case lid with the extensions blocks the pins.

I didn't use the pin extenders and made a frustrating trip to the computer store for some long spacer screws. I also ended up not using the pin header extension, had to carefully position my power and I2C pins before putting on the M.2 HAT, and pulling the wires out of the way. I'm sure it would be more frustrating if using SPI devices, as they take even more pins.

With those small modifications, the setup works if I'm not rewiring pins. The adaptor itself works great, the NVMe drive is lightning fast compared to my V90 speed SD card. The difficulty to access GPIO pins for future projects and too-short spacer pins combine to lose a star.

Was happy to finally have an official product from the foundation! Installation was a breeze and of course, native support with Pi OS. Everything working as normal, but faster. Only wish they either built it to fit inside the existing case WITH the lid on - or offered the ability to purchase (or print) a replacement lid that seats properly over the NVMe HAT.
