Hmm... I happen to like how yours looks
I guess the difference, aesthetically, is that instead of a giant, long run of tubing coming from the 5.25 bays down to the bottom UT60 240 res, it would simply be a very short 90 degree bend from the pump to the rad if mounted below the tube res. Also, mounted below the EK res makes the bottom of the pump get a HUGE amount of airflow, something that it wouldn't get in the drive bay.
On the other hand, with the pump in the drive bay it would allow me to have BOTH of my pumps in use... I just don't know if this method would be "good" or not: cpu-to-EK-to-XSPC(bay)-to-pumps (outlet of XSPC Bay Res would have a single Bitspower 90deg dual-rotary fitting coming out and pointing down and then there would be a Bitspower Male-Male rotary coupler attached to that; the first pump would attach to the Male-Male rotary coupler, making the pump parallel with the floor of the drive cage and it would have the outlet pointing "right" if looking from the very front of the case; then I would have another 90deg rotary fitting, single or dual depending on space, coming from the Pump Outlet, and then another male-male coupler attached to the end of that; Pump2 would then attach to that Male-Male coupler, also parallel to the floor of the cage, and would point "back" into the case allowing the tubing to make a clean run down to the bottom rad intake).
Doing this would allow me to have both a fill-port and a drain-plug off of the EK res, and I have the Bitspower ball-valve plug fitting for one, and the EnzoTech Drain/Fill Port Fitting for the other. I was thinking that for the drain port, I'd simply have the ball-valve fitting attached to the bottom of the EK res (with a G1/4 plug in the other end to be extra safe) so that I can simply attach a piece of generic tubing to a misc compression or barb, screw it in, then open the valve to drain. For the fill port, having the EnzoTech barb/stop fitting attached to the top of the EK res courtesy of a ~6" piece of tubing that can be tucked away, but long enough that I can attach another piece of tubing to it to ensure that the EK res is truly 100% full, and that while bleeding the loop the only "open" spot is 2-3ft away from the case internals. Does that work, or am I going about this wrong?
Sorry for the wall of text, I am just "stuck" with this :/
