If you're looking second hand :
Nvidia: 2060 or better
AMD : 6600xt or better.

I wouldn't bother with older generations at this point, I'd also be a touch hesitant to go with much newer, unless you're willing to bring the GPU forward to your next build.

How bright is the environment you'll be using it in & what is the cost difference in your region?

Personally, I'd be leaning towards the Acer. But if you operate in a really bright environment the AOC may be better for your needs.

HDR10 isn't that big a deal at the brightness the ACER is capable of, but is a nice to have, ditto HDMI 2.0, chances are you'll be using display port anyway.

I would avoid USB as the range is shit.

After that, I'd go for this : https://pcpartpicker.com/product/mMJgXL/edup-ep-9651gs-80211abgnacax-pcie-x1-wi-fi-adapter-ep-9651gs

It's $1 dearer than the slightly cheaper options, but it looks better & honestly that's all it comes down to, these all use the same intel chipset.

Just make sure you plug in the antennas for range & make sure to use the card-> USB header cable for bluetooth.

This'll be fairly straight forward.

• Case still has a PSU shroud to hide cable clutter.
• I've opted for an m.2 SSD so you don't need to worry about cables to storage.
• Air cooler isn't too big, so doesn't interfere with any other components.
• GPU is 270mm, case has 320mm GPU clearance.

All in all, it's smaller than an ATX case, but still very easy to build in with the components above.

I'd opt for a Ryzen system over 12th gen intel now. Similar cost, more performance, less power usage & an upgrade path.

I've opted for a microaTX case / mobo as smaller builds are a personal preference of mine.
