The PSU mounting brackets included in the Lack enclosure files don't accommodate the 5 cm wider PSU that ships with the MK4 from Delta Electronics (model #PMZ-24V240WDAL).
The original brackets consist of two parts. The larger, bottom bracket secures the bottom of the PSU to one of the Lack table legs. The smaller, top bracket secures the top of the PSU to prevent it from becoming dislodged or sliding out of the bracket. Unfortunately, neither of these parts works with the power supply that ships with the MK4.
I've modified the original bottom bracket to accommodate the wider PSU and created a new top bracket to secure the top of the PSU.
Let me know what you think!
