Doesn’t matter how you go about it the RGB lights will not stay off. Even called their support and they agent came out and said “it’s complicated it involves command prompts and even then they won’t always stay off.” That was a verbatim quote. I have a towel over the tower while watching movies as these obnoxious lights make watching anything impossible. DO NOT BUY ANYTHING OMEN.

Omen 40L is a solid pre built PC.
The 40L PC is great. The case stays cool under heavy gaming, and has a user friendly omen hub app to customize lighting. I’ve noticed two downsides. First, the front diamond RGB light glitches when putting the PC to sleep or during other common functions. The other downside is when you receive the delivery you may have to recable some cables as they were not aesthetic upon delivery.

Slow, slow, slow
This PC runs slower than the one I wanted to replace. Windows 11 didn't help speeds operations up, either. I was looking for a PC that would be snappy in getting things done, not this boat anchor.
