I’d just run a fan through a couple of extra holes in the frame… Easy – if you get the right voltage, you could just use the pi for powering it.

RE: Top 5 unseen modules
I have three:
Built in Calendar module - While it’s normally a display module, I use it in the background to handle the calendar retrieval for MMM-CalendarExt3 (Day mode), MMM-CalendarExt3Agenda (Agenda), and MMM-Multimonth (My own module for month mode because I didn’t like MMM-CX3’s month mode)MMM-CommandToNotification - Enables display of various features, including data for an non-published module I wrote to handle display of my local weather data from my weather station.
MMM-NotificationToCommand - Much like the previous - it will take a notification and issue a command to the system - I use it to adjust a set of LEDs I have rigged in to match the mode of my mirror.

RE: MMM-DHT22
@Jonae Nicely done.
I’ve used MMM-CommandToNotifcation/MMM-ValuesByNotification for mine, with MMM-Temperature prior to that. Nice to have a specific to device module, though. :)

RE: Backing up via GitHub repo
Here’s what I’ve done.
Everything I modify, including instructions for things that can’t be moved is stored in a “MyConfigs” directory on my harddrive, with symlinks in the original folder - so config.js and custom.css is actually symlinks in the magicmirror folders.
Modifications to modules that I do are all forked off the original and stored independently.
It took me literally 5 minutes to get config up again after a SD Card blowout…
Pros: no work to get unmodified modules and MagicMirror up to current.
Cons: remembering the dang symlink command. I’m gonna write a script.

RE: monitor - disassemble or not?
@thedoorsfanatic clearly you cut a wire when pulling it apart. use plastic, patience, and small moves.

RE: Do modules stop requesting API data when monitor is off or module is hidden?
@sdetweil I simplifed out the details on purpose… Trying to keep it simple, Stupid (KISS)

RE: MM keeps freezing
FYI. the bolt is still active, fresh copy of the OS downloaded from their website, on RPI3b+. whipped it together so to test for mirror frame placement.

RE: Forum updated - I could use your help
Perfect. Actually, it appears to be that case. Thanks!

RE: Transparent glass in front of Acrylic Sheet to hold it together ?
If you’ve got the sheet the right size, you shouldn’t need anything - the frame on top would do the job of holding it in place if built correctly. See standard woodworking videos on youtube for frame building ideas, or hit up a frame shop.
