Waterbox 100.3 owners please help with new build. Also help with equipment selection.

After zero help from the general equipment, hardware, and filtration section I am reposting here hoping to get some help.

I was in the process of building my very first reef tank. I was going to use a 40g display with a 20g sump. While searching for things on craigslist I came across a brand new Waterbox 100.3 tank only that i could not pass up an awesome deal.
If 100.3 owners could help me. I need the plumbing lengths for the overflow, Drain and emergency drain. Return length I could figure out.

Now I have to start all over and pick new equipment given the larger volume of the display tank. I need recomendations on return pump, skimmer, LED lighting, and powerheads. I would like to have a mixed reef tank with easy/beginner corals, anenomes, fish, and invert.

I plan to use the 20g sump I already built. Will this size sump be adequate for a 70g tank?

Here is what I was thinking of going with to give you an idea of my budget.
1- Varios 2 return pump $199
2- Bubble Magus curve 5 $199
3- 2 AI Prime HD+ $420
4- Have not decided on Powerheads. Would like to stay in the $200-$250 range for one or two.
I am open to suggestions if its within my budget. Where am I going wrong? Are my choices good options. I'm trying to stay in the midrange (price) on my selections.
Thanks I would appreciate the help.

Hi, I have the 100.3 as well.

Here's my build thread, you may get some ideas there, but there are many ways to go about things depending on the particulars of what you want to achieve.
