Im buildning custom loop in my 1000d.
Just for esthetics, I want to place one rad before the pump, and one horizontally right after.
Is it possible (pic)? Im a noob, just want to check with the pros first
Assuming your pre-pump res is going to be how you fill the loop then as long as you manage to get all the air out of the post-pump res you should be fine. If you're pressurising that second res with your pump though, make sure it's sealed well!
