Yep, the Pelican 1700. If you want to buy one and DIY the foam part, read on.
It comes with 3 foam layers. Using an electric carving knife I found cutting the foam in itself to not be that big of a deal, but was surprised how hard it was for me to cut straight lines.
I recommend glueing the cut-out middle foam layer to the uncut bottom layer, this makes the foam structure much more stable. When gluing both layers together, put the cut-out middle foam layer on the ground, then hold the uncut bottom layer with both hands to position it over the middle layer. Doing it the other way round (as I did it…) is way harder, as the cut-out middle layer is very wobbly, making it very hard to position precisely while holding it in your hands.
Doing a cut-out in the top foam layer (which required cutting the upper foam layer in two parts, which is best done at a foam shop) is not really necessary in my point of view, unless you have modules with really long knob caps.
