Sata cable

[Txe]

It’s been a while since I’ve done a build 

And I forgot do the sata cables come with the case or storage?

They come with the motherboard and PSU.

If you need extras they're super cheap on ebay or whatever.

As said, the cables can be pretty damn cheap if you're worried about not getting them or having enough. A while back I ordered x20 3 foot SATA cables for like $0.22 each or something from monoprice. Never will need another one lol.
