Need some help/advice...

So I have had this prebuilt since early/mid2016 and I noticed a build up in the reservoir just recently.  So I have decided to flush and redo the tubing in the system.  Of course there is no drain port but I do have spare Koolance QD's to aide in the draining.  At the provided Link I have some pictures that show the direction of the current flow. I am wondering if everything will still cool just fine if I reverse it to have the last item the fluid goes through be the radiator at the bottom of the loop and add a drain port there for future use.  Any help/advice is appreciated.

Loop order makes no difference as long as the res is above and before the pump, also why the long tubing runs? I would suggest to get a crossflow rad if you don't want the tubing to cross over the RAM or board that would help shorten things up a lot.

Awesome, thanks!  For now I will keep the radiators I have, but when I eventually upgrade my video cards /processor I may swap out the radiators.  This was a Digital Storm PC that I bought early last year.  I plan to keep re-using the case since there is plenty of room to work with.
