That's what I thought as well. Thanks!

So there are probably couple options on how to do this. One would be to use Rainmeter desktop customization. You can probably do similar with Wallpaper Engine ($5 on Steam). HWiNFO has addons for OSD https://www.hwinfo.com/add-ons/ (also the Rainmeter one). Another way is to use some software with more modern UI for starters. Like NZXT CAM for example. There's also app for Android which sends system info over wifi connection. Which you can customize to your liking, https://www.trigonesoft.com/index.php/download

Yep. Checked the monitor connection - no change. Cleared CMOS and now everything is fine, but still on the old BIOS version. That's for the comment.

This build will be OK for 1440p at 60Hz.

if you get the extra money, upgrade from the 1660 super to the rx5700 in @Plouffe 's build.

Sorry, bit it doesn't work like that. I believe the data simply gets mirrored.
Get a RX5700XT with a decent cooler (like the Sapphire Pulse). Save some money and maybe upgrade something else in the future. 

Ok, thanks for the fast answer.

This would work.

I believe the Strix is the best, followed by the pulse. I cannot say anything on value as you didnt give us prices.

Either way, you're not covered under warranty. AOC's warranty is for the original purchaser with proof of purchase.  You won't have that, regardless.

It might be a bit outside your price range, but have a look at the Corsair Crystal 680x. It coimes with 3 LL Fans, a lighting node pro and a fan hub plus plenty of mounting points for additional RGB. Tempered glass, looks very shiny.

How's this? If any changes are nescessary;
You can change the MoBo for one with WiFi, and remove the CPU cooler. You can also get a cheaper case.

I agree. Without a use case I could make something like this, because I want it to look flashy:

Samsung 970 evo If price doesn’t matter

I believe that that's fine.

one problem... it doesn't fit half of your coolers
 
I'll say the cooler master h500(m/p) in mesh versions, meshify c/s2, mx330, focus g, mb511, nr600, enthoo pro and i probably forgot many more, so you can always tell me what's up your eye
 
and i second the psu swap and gpu swap  by @Catchears

If you are set on an AIO, get the 280mm as intake. But a Hyper 212 should also be just fine.

Budget? Location? What will you use it for?
 
 
You will most likely be better off building a new system altogether.
