I've got it's kid brother - the 150cm long version. No major complaints, and my LFS supplied two XP2 filters instead of one XP3 so I probably got better circulation and had the (never actually needed, thankfully) redundancy of at least having some filtration if one packed up.
Actually, one minor grumble - the way the lights are arranged on mine is two big metal beams each carrying a pair of 120cm tubes, I think yours would be 2 x 180cm if the come that long? Anyway, the way these attach to the tank means they're a bit of a faff to lift off and to get the back one off (e.g. to fiddle with equipment back there) you need to take the front one off too. And given they're covered in condensation water this can get a bit messy. The hood area isn't very tall either, so I suspect using any alternative higher power lighting would mean doing away with the cover panels altogether, which to me makes the metal top rim a bit redundant...
Other grumble is that the tank really is designed to run in Rena mode - the end cabinets are big enough to house the filter supplied (and the extra one if you choose), but this pretty much uses up your "hidden" space - that middle section of the cabinet (and yours will be twice as wide as mine) isn't so useful I find, I'd rather the whole lot was doored-up as it were, then I could put a nice big sump under the tank instead of getting the little one I'm planning on right now. On the subject of using 2 externals, one downside is it makes it pretty hard to use an auto top-up as you've nowhere really for the water reservoir - my new setup means I have a 25-litre jerry can of RO in one cabinet and the sump will be in the other. Can't recommend top-up enough, for the cost of the Tunze Osmolator and a big water container you get constant water level and no more tide marks at the water surface.
And finally - if you're thinking you could convert to sump filtration just by using an overflow, forget it - unless you make your own. The Tunze and Aqua Medic models I checked out both require the metal rim to be less tall, so it's a hacksaw job looming for me at the mo...
