Here's a Trent 700 starter motor, IDG, anti icing valve and external gearbox:

The starter motor is on the left of the picture, the IDG is the black lump with wires on the right of the picture, the anti icing valve is at the top of the picture and the external gearbox is in the middle.
Also, the biscuit coloured area above the starter is the multi layer Kevlar wrap which goes around the fan case to (hopefully) contain a fan blade, or parts of, from piercing the fuselage after a failure. The small piece of titanium plate above the starter is to prevent pieces of the starter turbine from damaging the Kevlar wrap in the event of a failure. When a motor does fail, usually due to lack of maintenance/oil, it goes off like a huge Catherine wheel!
The unit, extreme top right of the picture is the IDG cooler which uses fan air to cool the oil.
