Put my final order in for the rest of the components and ek are shipping my 6990 block on friday. Have gone for:
ek nickel backplate,
another phobya 140.3 rad stand,
xspc d5 xtop v2,
primoflex pro lrt clear
and an assortment of fittings, some more 5mm leds and another temp sensor.
I have also ordered an A3 sheet of black acrylic to tidy up the back of the drive bays, i'll bend this using a heat gun and probably have some cutouts/holes for cabling.
