I did it box out. With hindsight, it might have been easier to take the engine/box out as a unit (they drop down) but I didn’t have a crane. You only have to disconnect a few more things than the gearbox to take the whole lot out, and then changing the clutch over should be easy. One thing I’m not sure about is where to disconnect the fuel lines. Also, you’ll need some sort of dolly to roll the lump out from under the car.
The hardest part was getting the box back in place. I followed this guide:

I left the DMF in, as it was in good nick. Many have opted for the solid, but if you go for the DMF again it’ll be stock, as designed, and will outlast the rest of the car most likely.
