Some thoughts about the rad issue, relevant or not you to tell...
- 140mm rad with ports on the opposite side (PSU side)
- 140mm rad with ports on the opposite side (PSU side) / 120mm slim fan to allow routes for the tubing above the rad if needed
I know you are going to ask a lot of cooling to the rad already, but maybe a 120mm radiator will not loose so much on heat dissipation vs a 140mm one. Lots of people are saying the fan is more important...
- 120mm rad to allow enough offset of the blocked port
- 120mm XSPC thin rad (20mm) to gain 10mm if that helps with the port
- 120mm XSPC thin rad / Noctua fan NF-A12x25 for better airflow/pressure (if there is room for the extra 2mm, 20+25mm vs 30+13mm)
- 120mm rad with ports on the opposite side (PSU side)
- 120mm rad with ports on the opposite side to the motherboard, if enough room
