Okay so tax/shipping included the final toll looks like this (and I mean EVERYTHING, need more wire/Wagos/thermal tape since it can't hurt)
548.63 (8x 3000k from arrow, 8x 3500k from digikey)
If I did it using just the 3500 strips from digikey the build would come out at 496.56.
That's making the entire frame out of angle aluminum from Home Depot. Have to wait til the local aluminum framing specialty shop opens to see if I can get it cheaper (or make the cross pieces out of U channel instead of angle aluminum).
