I'm start with the loop and I decide to going with minimalistic and in some way non conventional loop, just 3 tubes, the other connection are made by fittings and adapters to achieve an industrial look I think, this is possibile due to the "parallel loop" and crossflow radiator which allow me to reduce the number of tubing and tubing bends.
The front panels are missing because the first panel with the mounting holes is at Parvum HQ for rectification,
@imersa told me that maybe there was a problem with the shipping, so i'm still waiting to receive it.
Btw even the front loop will be made by only fittings and everything will be super tight.
