Grizz's 300 gal 8'er / LED Heat sink build / Opinions on LED lay out needed

[The Grizz]

So here is a concept design of the 300 gal 8'er that I am planning to start in Aug. Tank will be 96"L x 24"W x 30"D, 3/4" all around, euro-braced & starphire front. I am tossed between putting a wave maker on the left end or getting a couple MP 40's. No closed loop but I will be using my OM 4 Way on my 8 return lines. Also going to run my skimmer, 2 - MR1 reactors off my return pump, add in a ATO & WC system from my water room downstairs. Definitely going with LED for lighting and hope to have a 4 pump doser to go with my Profilux 2EX controller.

This is just the sub frame built out of 1 1/2" Hss for the stand & 1" for the rest of the cabinet which will be skinned with Burch & Oak.

So what do you think? Did I forget something or do you have any ideas for me.

Could not figure out how to upload this pic to photobucket from Google Sketchup so I just took a pic with my phone.
