As others have said, congrats on the new build :)
I assembled a desktop* for myself in 2021 after a long run on an ol’ Dino Laptop. I had similar feelings - a LOT had changed. I was able to avoid RGB for all the internal components, but it did take some looking.
RGB lights on memory, etc. look nice if you have a window in your case and keep it on your desktop - doubling as artwork. I’ve seen some very pretty-looking builds out there!
*Deskbottom would be more like it. I keep the case on the floor under my desk.
