what is a cheap way to mount these suckers, cheapest i can get aluminium angle is $40 per 6.5 metres, would cost me like $60-70 per frame, i ordered the samsung 2 foot strips, single and double row strips which are approx 16mm and 40mm wide respectively, ive looked at flat aluminium sheets wich are 1.2metre x 2.4 metre lengths which cost around $80 each, i just need to cut those down to 600mm x 800mm or something similar, but would cost me $20-25 each for 4 heatsinks, anyone have suggestions? > i plan to run these fairly soft so wont need anything overkill <
