A valid question Gone_fishin.
Since I've opted NOT to put the pump at the bottom of the case (because it may interfere with the PCI slots), I'm left putting it as shown. The tee at the pump inlet is for a ball valve, for draining, but since the pump is no longer the lowest point, the tee will be removed and put somewhere else in the loop.
However...
The pump in that configuration may get in the way of the block and res! So if need be, I'll bolt the pump vertically on the side panel (inside). "Little Giant" specs state that it is OK to run it in any orientation.
Since I've gone to 3/4, I am going to pick up a volute for a Little Giant 3-MDQ-SC (once dimensions are confirmed, thanks to Hellion_Prime), which will give me the 3/4 inlet and outlet that I want on my 2-MDQ-SC. It may also resolve any issues that may come up with the small inlet.
Hopefully, this will not affect pump performance/specs: the 2-MDQX-SC has that volute, but is rated for lower pressure.
