Ha ha, thanks. Yeah my fingers were chewed to bits
Honestly, this has been apart and back together so many times it's ridiculous. The motherboard is the last component to go into the case typically because of how everything is routed behind it.
I've had my ups and downs with pastel coolant. My takeaway is to make sure everything is really clean and has no debris. I've got another litre of white pastel which should do me for another couple of flushes yet and my intention is to replace it every 4-6 months anyway.
I quite like the idea of either getting some dye for the coolant or swapping the CPU waterblock and RAM for white variants, we'll see. I'm also not keen on the fan power/rgb connectors near the window, I might see if white versions are available instead.
