Go to pacific lighting concepts website and it will have literally everything you need.
Look up cree cxb3590 datasheet, you can find the given voltage of an individual cob at the target/given amperage (you can multiply these 2 together to get how many watts each cob will draw, ex. 30V x 1000mA= 30w, 30V x 700mA=21w, etc etc)
Then when you figure out how hard you want to drive them/how many watts you want/how many chips you want to use to get there (< all the same process) you need to add up the total volts of all the chips together (30 x 4=120V)
You will need to find a "constant current driver" that can hold your total volts and drives the chips at the amperage you want (700, 1000, 1400mA..etc) the closer you are to filling up the full voltage of a driver the more efficient it will run.
After that it's just figuring out if you want to actively or passively cool the panel and pick a form of Heatsink (one large slab, or multiple smaller cpu style) and pick fans if you want active
These wonderful guys skipped all this for you and named the part #s you are going to want to look for, again, hope over to pacific lighting concepts and they should have every piece you need to go start to finish.
Good luck buddy
Edit; none of the example numbers I used match up in reality- I just used whole, easy numbers for examples sake
Edit II: there are holders called ideal chiplok holders thay have respective part numbers for different cobs, you'll want to find the one for your specific chip, again, plc should be a one stop shop for you
