You're going to need more than 6 hp of free space, for starters. What's happened here is that you're trying to cram too much function into too small a case. It might seem cheaper...but when you arrive at a basically-unworkable result like this, you start to see how things get unnecessarily expensive or annoyingly tiny...or both.

If this is still a MG build, scrap it and start over in something that has a more practical amount of room. Things like the Pods really exist to house "orphan" modules alongside other rigs; they're not a nice solution to making a small modular.
