Thank you for your cool device!

3 days ago I received a delivery with a HATDrive! Top and a HATDrive! Bottom. Both work super fast and I'm impressed from both performance.

Not sure, if you are planning for a 3D printable case. But it might be an idea do move the drill holes of the HATDrive! Bottom a bit away from the USB-sockets, so the whole PCB doesn't stand out "on the rear" and also do a FPC, which doesnt cover the SD-Card, since you might need it for booting one time to set up the nvme drive...

Another customer friendly thing would be to provide 4x extra M2.5 stand-offs to not let sit the NVMe drive on its chips. If you would move the FPC tho the side, a M2.5 nut could be enough to keep the distance to the Raspi PCB and a female stand-off would take the bit longer M2.5x6mm screw to keep the bottom away from the housing.

Best Regards

The Hitchhiker!

Suggestion for additional bottom stand-offs:

Competitor moved the PCB more towards the USB-A sockets to have a "flush" backside and moved the FPC out of the way:
