I built this for my external box for water cooling my system. It holds a bit more than a quart. Dimensions are 2"x5"x8". It has two tabs on it to attach it to the side of an external box. There are 2 3/8" barbs jb welded to the 90° elbows. There is a whole in the top for filling. I used it for about 3 weeks and never leaked.
I am using a different one now.
