1/2" Tubing too thick?

[B3NDY]

So I am looking to make a custom loop in the Enthoo Primo and was intending on cooling the CPU and GPU with 1/2" tubing between but I was wandering if it will look a bit too chunky. I'm not too keen on thick tubing but I don't know whether it will look as thick in this case.

The problem is that I have chosen the swiftech MCP655 which only has 1/2" fittings so I'm not sure whether other tubing would fit.

Also what other sizes are there?

7/16" ID tubing would be the only other tubing you could use. But, frankly, there's not gonna be much of a difference size-wise. Also, you have to pay attention to the OD. You want to have a relatively thick OD compared to ID so as to avoid kinks in your tubing.
