For the Pleb home heating miners I found a nice 24”x16”x10” metal box from Vevor that fits an S19 nicely. The box has nice door seals and looks clean when installed.

The primary goal was to provide some level of fire protection and secondarily to reduce noise - especially the high pitch PSU fan noise.

A zip wheel in the grinder quickly cut out the ductwork holes (a hacksaw and drill would work too) then metal foil tape was used to secure the ductwork and cover the sharp edges of the power supply & ethernet hole.

An old exercise mat and some foam along with leftover styrofoam from the Vevor box packaging was cut down (and wrapped in foil tape) to help provide a cold/hot air barrier. An air filter was also cut down and added to the intake side.

Some redi-rod was cut to length and four holes drilled into the top of the box to allow it to hang from the ceiling. BTW the box comes with other hardware to bolt it to a wall if your install allows.

Note: the 6” ducting and 6” Cloudline fan from a previous S9 build is a bit small for the S19. At 2200 watts and with the Cloudline running at 100% the S19 factory fans run at 45% (this gives 84TH/s, 60c chips, and ~25W/Ths).

By far, most of the noise is the Cloudline fan. The PSU can’t be heard anymore. I’m sure an 8” fan (or bigger?) for extraction/ventilation would lower the noise but check the dimensions of the box to make sure it will fit.
