This was a high-end Origin prebuilt that retailed for almost $8K. It was pretty ho hum, no custom cables or even extensions, and cable management was mediocre for the price point (baseline pics at the end). My client asked me to pretty much start from scratch and make it look like the beast it is. The lengthy parts list is here: https://pcpartpicker.com/list/hcLJC6.

It came with a 480mm/54mm thick rad, we added a second 360/54mm up top. Neither god nor man intended these two to fit in this orientation, but my client insisted this was how he wanted them. I had to use a 15mm slim fan in the top position, move the 360 slightly forward, and still had to shave about 3mm off the rear of the top right QL120 fan.

Other changes included a new pump/res, hard tubing with gold fittings, an inline flow meter, and an EK Lumen stats display. I made all the cables, as well as shortening fan and RGB wires, the PSU's SATA cables and converting the pump and flow meter to SATA rather than Molex. I also removed the Corsair RGB strips and added my own - their failure rate is terrible.

The Corsair Shift PSU uses MicroFit+ connectors on the PSU side; once I found a source for them they're easy, same technique as with the usual Micro-Fit connectors.

We switched fan control to the motherboard headers, as I and my client trust the bios more than iCUE for fan control. The D5 pump only gets about 2L/min flow, but temps are ridiculously good. GPU never goes above mid-60s, CPU under heavy load hits around the mid-70s.
