Looks good.
Just IMHO I like tygon tubing, have used it for years and I know others like other tubing but that's just what I like using.
The barbs should be any that will fit your components since they are usually chrome plated or similar so you don't have to worry about dissimilar metal corrosion, just make sure to get 1/2" ID on them and choose the high flow ones if you can.
What reservoir are you going with or are ya gonna do a T-line?
Also what fans you gonna go with?
