Some ideas about watercooling.

Thermal load and capacity

• Estimated heat load is ~325 Watts
• At best I can fit 2x 120mm rads in the case

This is all estimated with EK's Configurator tool.

Final build

Going around the loop, in rough order.

• Corsair 280mm radiator
• Corsair ML140 fans (already had)
• 2x Barrow 45 degree fittings
• 2x Barrow tube fittings
• Tubing
• 2x Barrow QD sets
• 4x Barrow fittings on QD
• 3-way rotary tee joint
• 1x plug for tee
• FLT120
• 1x Barrow 45 degree
• 4x EK torque fittings
• 2x Barrow 90 degree gpu
• Bykski gpu block
• Bykski cpu block
• 4x Corsair fittings
• Barrow octa res
• 1x Barrow 90 degree for octa res
• 2x Barrow 90 degree on fill port
• 60cm fan extender
• 2-way fan splitter
• Temp probe

Reordered and collected, that's:

Cost estimates

Barrow makes some cheap options that perform well, may be a compromise on appearance or quietness. The premium option is of course EK or Alphacool or whatever.

This doesn't cover the fittings and tubing and all that other stuff.

Also, I won a FLT-120 w/ D5 pump off ebay for ~190 AUD, whoo!
