- Give a thought to power. Are you routing the power through the wall? Through a hole in your internal framework? Consider that at the moment, you have to power the Pi and the monitor, so that’s two cords.
That is a good keyword. If u just want one cord u can think about using a step-down converter.
Don’t know what Voltage your monitor will be using. In my case my monitor needs 12V and the RPi 5V as normal.So i choosed a big 12V power supply (5A or 60W) to power both.
Then i ordered a DC-DC Step Down converter: https://www.amazon.com/DROK-Converter-Step-down-Regulator-Stabilizer/dp/B019RKVMKU/ref=sr_1_5?ie=UTF8&qid=1516968110&sr=8-5&keywords=lm2596&th=1
connect the 12V output of the power supply to the converter input and parallel to your monitor.
adjust the converter output to 5 - 5.1V and connect it with your Pi :)You can see an example here: https://forum.magicmirror.builders/topic/6048/my-first-mirror-until-now/12

Or, you can do it the lazy old man’s way. :-)
Mini power strip (inside mirror frame) your monitor and Pi both plug into and you still have an outlet available for something else. The power strip has an on/off switch which comes in very handy as a power switch for the Pi and only 1 wire comes out of the frame from the power strip.
Peace!

Hmm I may go that route. I like how well contained everything sits in your rig.What I should have put in my original parts list is that I snagged one of these guys Cablelera Power Cord Extension and Splitter, NEMA 5-15P to NEMA 5-15R x 2, 16 AWG, 13A, 125V (ZWACPQAG-14) https://www.amazon.com/dp/B00FRODUR4/ref=cm_sw_r_cp_apa_Hh2AAbABEH35N (sorry, on mobile) to deal with the power issue, though it miiiight not be the most elegant solution.

Advantages:
When you shut down your Pi how will you turn it back on? Pull the plug and plug it back in? Hell no! A (mini) power strip with a breaker switch works perfectly. Turn the switch off (after shutting down your Pi) and simply turn it back on. Boom! The Pi now has an on/off switch.
Extra outlet. After you’ve plugged in your Pi and your monitor, what then? My mini power strip has three outlets. That’s all I needed, but as builds become more complicated and require power for other devices (LED’s etc) then a six outlet strip can be affixed to the wall of the mirror box. Mine is on the bottom.
Less cabling. With the power strip you can modify/make extensions of exact length so there’s less clutter behind your mirror. I made a short orange extension (see picture) because the power plug for the Pi “stood up” when plugged in. I couldn’t have that. Now it “lays down”. Yes, you could do that without a power strip but do you really want to splice all that wiring? And how would that look? Hell no! (I like saying that) :-)
This is just my opinion, and others may offer you better solutions, but I think this a very efficient and neat way of doing things, and you get the added benefit of an on/off switch.
P.S. At the time of this build the mini power strip was a $5 add on item at Amazon. You can’t beat that with a stick. :-)
Peace!

@Mykle1 Awesome, thanks for your thorough response!
I’ve hit a snag with the monitor, I don’t know how to get the bezel off. Videos online for this same model (but apparently different sub-model) have screws and clips in places where mine does not. I’ve got the Acer AL2216W sd. Would it be ideal to just use brute force on it? Hell no! There’s gotta be a better way, but I haven’t found it. I ordered a jimmy and may just wait for it to arrive to try and crank that thing open. Any advice would be much appreciated :-)

Ha ha! :-)

I’ve never encountered a bezel that didn’t just snap off so be as careful as you can be. I know someone that cracked a 32 monitor while removing it from the casing. :-(

This looks like the way to go, though perhaps a bit more advanced than I am. I think I’ll give this a go when I build my second mirror :-)

a last hint, which is more software suggest:
https://github.com/gilyes/pi-shutdown
order one push button more (if u tough about before), so this is nice to shutdown and boot up your Pi safely :)

@Mykle1 Could you show me how this mirror looks from the front? Do you have it vertical or horizontal?
