Update! The new cables definitely bring it together. Not sure why the RGB on the Lian Li Strimer cables isn't working, I must've messed up somewhere. Even without it, looks a lot better and the PC runs perfectly.
Yeah, I got lian li's strimer cables for the motherboard, and a plain white cable extender for the gpu. It's hopefully being delivered tomorrow so I'll send an updated picture once I've sorted the cables out.
PCS sent me a 3d image of my build, thought I'd share since I wasn't able to find any pictures of all white builds on here when I was looking before ordering. I do have some white cable extenders to replace the black ones with but wow it looks amazing. Thank you PCS :love:
