Where to mount new Powersupply?

Talk to azerate, I think he posted his printer over in projects that has the PSU mounted on the back of an SD2.  It's crowded, but it works.  One thing that I have learned is when modding or building a printer, it is worth it to take the time the first time around to make the wiring tidy.  It is more inconvenient to do it twice.

I made "Risers" and mounted them underneath . I use 2 power supplies 1 (30 amps) for heaters and 1 (12 amps ) for everything else. I also have built a remote control on / off power box ,and an independent monitoring system for both power supplies voltages and currents, bed and extruder temps as well as LEDs to indicate when SSRs are on. All of these are on Thingiverse. Enter  "divemasterbill"  in search bar (leave out "  ") these and some other mods will come up. any questions just ask.

I put everything on a plate, bolted to the bottom of the printer, and made a skirt thing to hold it off the desk and mount switches / connectors etc. in. Works pretty well, but if I did it again there would be a drawer and a few more connectors involved.

                                                                                                                                                                                                                                                      If you mount SSR's to the back of the case the whole case IS your heat sink. I used heat transfer compound( white stuff you see used in computers between CPU and heat sinks.)
