In my opinion the biggest advantage of both of these kits is that they come with cases. For me designing the case was the biggest challenge in my first build. I had to plot where all of the parts will sit and had to account whether they intersect or not. Then I did a CAD drawing for the CNC and so on. You could also get one of the AMB kits if casing doesn't scare you. Actually there are plenty of Chinese cases prebuilt with IEC inlets, RCA's, TRS and volume pots. These usually need very little work, assuming that everything fits in.
