Any tips on cheap desktop (not rack) hardware products, that have real-time spectrum analyzers and/or peak level meters? These could be a cool addition to many systems. I personally miss the spectrum analyzer of the RME ADI-2 Pro I no longer have...

There are many DIY LED kits for example on eBay but I am looking for maybe a bit more PRO device...

I have tried. No luck yet. That's why I am asking for tips.

Budget?
There's this after a quick search: https://www.sweetwater.com/store/detail/U70F--fredenstein-u70f-led-peak-program-meter
I am sure there are much cheaper options.

Cool. Is it a Pi board?
LOL, NO!
It's an iPhone 4s or 5 (I forget) with a $4 app called Spectrum which also does octave, FFT and spectral plots in various ways that I use on my current phone. I'm a bookbinder and printer so wrapping it up in some book board and pleather took about 10 minutes. Just made this prototype earlier this week when I saw someone else posting about the expensive single purpose boards on eBay from Asia.
Who among us on this list doesn't have a few old smartphones in a drawer? You could buy an old iPhone for less than one of the "new" OLED screen toys and use it just for this.
I thought briefly about marketing the enclosure but that sounds like a nightmare with all the different phone sizes and shapes so I'll let someone else steal this idea and stick to making books.

Yeah, but it has tubes...

LOL, that's an unused little tube buffer sitting behind the display. Great idea though - little led light on top with a tube glued on it and I could charge $200 instead of the $20 I was thinking...
Here are some better pics. Anyone should be able to figure out the basic pieces based on these and make one for themselves:

Nice!! This is an innovative idea and I do have several old iPhones laying around in the house. Kudos to this DIY!
Does this power up like a dedicated analyzer?
I found the Android phones allow you to alter the boot manager and launch the app at start. I have a couple of old iPhones and at least one iPad that I could use for this.
I don't think it's super accurate because it's using the phones microphone so whatever limitations might be involved there and phone placement - thus the perforations on the enclosure where the mouth would be. If there were a way to bring audio into the phones I'd suspect there's enough computational power.
Edit: It was a fun toy for the desk but discovered phones don't like to be plugged in all the time so too much fiddling with rebooting and such.
