Upside Down Edition: AMD BC-250 Easy Print Better Cooling Flex ATX / HP Server PSU Case V1.4

V1.4 - Thanks to community data sparked by OldLamer, it has been noted that all BC-250s have marginal to substantially better cooling performance when "inverted" from the typical vertical position. V1.4 swaps around the feet and handle (which has been bulked up), and adds surfaces to support the card should the screw back out while in the inverted position. For those who prefer the old orientation, simply use the V1.3 files and optionally print the handle from V1.4 instead.

V1.3 - Minor QOL tweak on side panel holes. Alternate back case for HP Common Slot Server PSUs (HSTNS-PL28 and others sharing the same form factor)

Borrowing some design language from @SebastienGau_4340160 minimalist case, I wanted to create a case with better cooling and centered fans. Airflow is optimized and even on stock pads/paste, I get very good cooling on my unit with the center fins straightened.

Some countersinks and other features have been skipped in favor of being able to print everything without supports on common printers

The case takes 10 M3 heat inserts (5mm OD, 4mm length). The top handle is optional as the lower screws on the front and back panel should hold everything together well.

There is room for an up to 20mm heatsink on the backplate when using a 25mm fan on that side, but it may be a bit tight.

A 16mm front button is assumed but options for other sizes on request.

The 4 main pieces slot into each other.

Make sure that your printer's hole compensation is decently tuned.

Multiple styles of feet are available, "sleds", individual feet, and just not using any at all.

Two snap in screw hole covers are included.

PETG recommended. ASA may be even better but probably isn't worth the hassle.

Later revisions have been updated to hold the sides more tightly to the front and back sections for a cleaner look.
