Udev rules should be patched for OpenRGB to read/write to I2C devices (i.e. Aura DRAM's). Group 'i2c' does not exists in ArchLinux, there is no 'uaccess' for those devices and there should NOT be: I2C devices should only be accessible to a high-level users group for security reasons.
IMHO you could remove 'plugdev' assignments altogether (since we have 'uaccess' there), replace 'i2c' group with 'wheel' and chmod 660 the devices. This is how I fixed it on my workstation:
$ cat /etc/udev/rules.d/custom-i2c.rules
KERNEL=="i2c-[0-99]*", GROUP="wheel", MODE="0660"

Thanks for the dependency tip, Cyring; I've added them to the PKGBUILD. I disagree with your second part regarding the rules file.
The rules file doesn't need editing to work; you don't need to be added to the storage group. Any errors in your log are harmless regarding the plugdev group because TAG+="uaccess" handles permissions on recent versions of systemd/udev. The plugdev group is for Debian et al. & is ignored on archlinux with systemd.
Additionally, i2c-dev should be loaded on boot by installing this package & i2c-piix4 is loaded by default on my system (& presumably others' systems).

Using a fresh Arch setup, you may additionally need:
pkgconf
i2c-tools
ldconfig
As mentioned in other comments, a service to care about:
modprobe i2c-dev
# find and replace group plugdev with storage in 99-openrgb.rules
# then add user account to storage
cp -v openrgb-git/src/openrgb/99-openrgb.rules /etc/udev/rules.d/
udevadm control --reload-rules
udevadm trigger

Might be nice to add in a .service for loading a default profile on boot.

Hi Myrddin,
I have a Corsair K70 RGB LUX keyboard which have different product ID than K70 RGB keyboard. Could you please add below udev rule to 99-openrgb.rules file.
# Corsair k70 RGB LUX
SUBSYSTEM=="usb", ATTR{idVendor}=="1b1c", ATTR{idProduct}=="1b33", MODE="0666", TAG+="uaccess"

Okay, thanks. I checked the link with the fix and it appears that it wasn't merged, which makes sense because currently, it's still conflicting as the package stands. Additionally, commenting out the udev rules doesn't work either. The conversation I had with the developer stated that the way to do it was to remove it from the build process. Since you can't test it and see, I'll leave it at that and sort it myself. Thanks.
