Indeed lol. I'm subbed up now! Will you be doing a grow with it afterwards on here?

Youll want to do 4 cobs probably, 2 1212s and 2 1812s, wired in series to bring the voltage up to around 84v / driver. Because you have a pretty hefty fan compared to the wattage youll be using, you could probably get away with using a chunk of sheet aluminum with some smaller heatsinks attached to it. If you can find someone to cut u a piece of 5mm sheet aluminum and mount the cobs to it and then add a few heatsinks, like these http://www.ebay.com/itm/DELL-COMPUTER-SOLID-ALUMINUM-CPU-HEATSINK-Lot-of-5-Small-Various-Sizes-/122159713199?hash=item1c71494baf:g:MXYAAOSwmLlX7p3C preferably over the cobs, youd probably be fine. Thicker metal will make placement of the sinks less important. Most sheet metal places have scrap bins where they put smaller chunks of metal they would give to you very cheap. Actually cutting aluminum is pretty easy, you could do it on a table saw with an abrasive blade if necessary. Check out your local metal recycling shops also, you can get some great items there, if they will sell direct to the public.
You dont need so many cobs, one pack of 5 is plenty, Id get 4000k for veg. You can run 2 1212's on each driver also, that would work fine. There are gen 6 citi cobs available at some places now that give a little performance boost, if you can source them.
I have both a 48 and a 96 that could be upgraded ... i will be watching and then blantently copy
