Flow order for this lot, any direction?

[Danfoss2011]

Setup...

EK-Supreme HF
EK-FB ASUS Crosshair 4
EK-RAM Dominator
EK-FC5870 V2
Black Ice GT Xtreme 560
Tygon R3603 3/8"ID (1/2"OD)
1/2'' G1/4'' Fatboy Barbs All Round
EK-DDC Dual Top V2
2 18W DDC (DIYINK PCB's)
Swiftech MCRES-Micro Reservoir V2

The rad is external which is 4ft away so 8ft of hose alone there.

Pump & res are within the case.

This is all as one single loop.

How should i go about direction of flow.

Would you not be better off using 7/16 ID 5/8 OD over those 1/2 barbs?

3/8'' ID fit really nice and tight on the 1/2'' fat boys, it looks good and 3/8'' gives really good flow to temps per the tubing test on XS. Plus i don't have to worry about hose clamps, the bend radius is nice and tight, also the presure raiting is high as alone with stock DDC 18W X2, rad and cpu block i''ve got 10 PSI in the system when running and 4 PSI static. I've also a box of the tubing that some tart in the office ordered by mistake and is of no use so i took it home (im the boss)
