ok ... here's the deal ... for the newer monitors your not going to need a isolation transformer or inline fuse. Also they come with a power cord to plug directly in a outlet. (unless your monitor manual states otherwise)
its just a terminal block ... basically so you don't have to stuff multiple wires under one terminal ... really a personal perference and not a requirement

... as for the AC filter ... not neccessory if you pluging your components into a surge protector inside your cabinet ... that better safe than sorry theory

basically you can make a power cord for your PSU, Monitor (should come with one if you can plug it in directly), and lighting. Plug all that into the protector and your set.
btw ... how do you like your Deluxe JAMMA harness from X-Gamez (nice isn't it)?
