Red Sea E-170 Equipment Upgrade?

Well, it has been a while since I have been here. My MSc dissertation took over my life for the last 5 or so months...

I am just considering options again with the intention of purchasing this week really. I was considering going for an Aqua Nano 100l with Kessil A160's and a Vortech MP10 etc but have just seen the E-170 on Charterhouse (http://charterhouse-aquatics.com/sh...s-170-aquarium-with-hydra-26-light-unit-black). It seems to have several bits of equipment with it and I was just wondering if you would recommend if any of the equipment would need to be changed or if I needed additional equipment for it as it is fairly expensive as it is. Would I need an additional pump/wavemaker? Or anything else? Is the skimmer up to muster or would I need to purchase a replacement? Any advice is massively appreciated!
