first reservoir

JUST PUT OLD 7900 WB ON EVGA SC.sli setup
I have only used a T line on sump [pump in] for 6yrs.
Now i got a DD bay reservoir to put in also
Does reservoir go were T line was on pump in?
I see no reason why i cant put reservoir on pump out to radiator.
Were best place to stick the lines.

In order:

Reservoir --> Pump --> Radiator --> Waterblocks --> Reservoir

Reservoir --> Pump --> Radiator --> Waterblocks --> Reservoir

thanks
