good on you for willing to spend the money!
like most hardcore marine people will know that this is not a cheap hobby from setting up, maintaining, live stock...etc
Drilling and sumping is highly recommended but the only thing is that the juwel cabinet isnt the biggest so your sump design will be limited. Brands that i would recommend would be deltec, tunze, ecotech vortech
take it slow, do alot of research and have fun
good luck
