How does an all white PC build with black psu cables look like ?!

I am building my first ever PC, and I wanna know what are the pros & cons of a white build

If anyone has same build like with Black cables feel free to show me the image here, then I can see if it matches my imagination.

White case with white ARGB fans, white ARGB cpu cooler, black & white motherboard, white GPU and black psu with all black cables.

Is it necessary to go with white mechanical keyboard too? To match the aesthetics, Also what about mouse pad white or black?
