Looks like a nice little setup mate, but I'd make a couple of changes to it myself. The Laing DDC pump that you've chosen will be fine for your CPU only loop, but keeping the stock top on the pump is a bad choice for two reasons. firstly the stock top has 3/8" barbs (you need 1/2" for your tubing) and the only way around this is with an 'alternative top' (check in the same section as the pump on WCUK website). As you're using a highly restrictive block like the EK Supreme you'll need decent flow and 'head' pressure, and an alternative pump top like the XSPC one will give the pump the extra ooomph that it needs.
Are you using the anti-kink coils for looks only? If you think that you'll need them for that XSPC tubing then you won't as it has thicker walls which allow for better handling of tight bends. As a result you won't need the coils unless it's purely for aesthetic purposes.
