Noise:
The silver keys on this do not create a audible or tactile click per se, though if you are coming from a membrane keyboard it still makes far more noise just from the impact of the keys against the stops, something to consider if a quiet keyboard is an absolute must. While you can technically type quietly, it is completely impractical. Quiet for a mechanical, but still noisier than membrane. Just be aware if this is your first mechanical.
Keystroke:
The other thing to know about these keys is the keystroke is short in length and fairly light in resistance. Because if the shortness of the stroke, the perceived sensitivity is much higher. Accidental keystrokes may be more common, at least at first. If you suspect you'd like light keys and are a fairly proficient typer who can probably cope with the added improvement necessary to avoid accidental keystrokes, then you'll probably be just fine. After some practice I feel like I can rip much faster then a typical keyboard and could probably go with even lighter springs now that I've tried it.
RGB & Software:
Yes, this works out of the box with the latest version (try gitlab) of OpenRGB, and it looks great with Keyboard Visualizer. EVGA's Unleash software is also decent. You can pretty quickly set up different profiles that each have easily adjustable layers where you can select the usual aesthetic effects, static colors as indicators, or toggle-able colors based on keystroke.
You can also set up custom primary and secondary function key assignments as well as macros. I suspect not too many people would specifically use Unleash for this purpose, but it's nice to have.
Other:
The roller volume control is very responsive and smooth. The magnetic wrist rest is actually pretty nice. The chassis and feet seem pretty solid. The EVGA branding is to damn big.
If you want an affordable fully RGB light, short, non clicky mechanical keyboard, this is a serious one to consider when discounted.
