Maybe you already have something else planned for the VESCs but they obviously won’t fit into the rear enclosure, so you need to cut the shrink wrap off the back and bend the capacitors over the VESC pcb. I used zip ties but you could use rubber bands as well to hold the caps to the pcb. Then on the side of the pcb that still has shrink wrap you can Velcro it to the deck. It’s best to secure everything in the back to the deck because it’s a really small space where the phase wires enter the enclosure, so you can plug in the wires and just Lower the enclosure over everything. Also in the front there is a small gap when you are standing on the board, right behind the front trucks so if you have the choice try not to put wires up there because sometimes they can poke out of the enclosure and get damaged. My build is just about the same as yours, but with lipos
