More for the Maximal package. BIg SSd-s seem to draw siginificantly more power than the smaller ones. I have tested 3 types of 1 TB SSD-s with this setup so far: GOOD: WD Blue 3D NAND Internal SSD 2.5 Inch SATA - 1 TB BAD: The power was a single 3A Pimoroni PSU from the shopping list for all. The X825 board can be powered separately too with a 5V barrel connector in case that would be needed in the future. Already very useful when cloning the disks. |

Link to a build with the X825 board, heatsink-case and 22mm * M2.5 screws working together well: Fits the metal case too. |

Use this board from Geekworm and you won't need the SD card any more. https://geekworm.com/products/x883 You will also need one of these to connect power to the RPi - |

In connection with the metal case (https://diynodes.com/product/zkds-metal-case-for-the-raspiblitz/) I have been experimenting with this SATA-USB expansion board and found it very stable.

It has 2 pairs of 5V power pins too, so there are more options to attach a fan.
This one seems to be good quality, silent and efficient (keeps the temp at 58-62 degrees max with repeated stresstest runs
./config.scripts/blitz.stresstest.sh):https://www.ebay.co.uk/itm/Fan-Square-Cooling-Fan-with-Heatsink-Cooler-Kit-For-Raspberry-Pi-4-3-V-df/372980446235
It sits on a heatsink which has a sticky layer on the bottom.
there can be plenty of similar fans be found on amazon/ebay/aliexpress.

Square Fan Rasperry PiI am also using some 22mm x M2.5 screws (with M2.5 locking nuts) to support the screen from below. This keeps it very stable when pressed.
