SFX Supply enclosure

This is an enclosure sized after a SFX power supply.I am assemblying a DIY NAS using a case with SFX PSU support, using a motherboard with 19V supply input.The motherboard cannot supply power to all the six 3.5" drives, it requires external electronics.Therefore I designed this box where I will put the two DC DC converters, to use the space of the SFX supply.In the attached 3mf model i have put the holes for the 19V power plug and switch that fits my needs, but attached you can find the SCAD code that genrates the box without any installation holes, only with the grills.I have printed it in PETG for obvious heat reasons.
