have had my PSlate cables in the cupboard ready for months now wasn't too bad actually, i ordered them before we could even order the cases $116AUD inc shipping for 24pin, 8pin CPU and dual 8PIN PCIe, the case is the last part i am waiting on bar water fittings, though i am slowly being tempted to ditch my plans for the LTsolo block i have and go an EK block and separate pump, or that Barrow pump block combo instead. I cant get a waterblock for my 1080ti Tubo (asus card) so the initial loop will be cpu only till 3090 (more likely wait on big navi)
FYI the Barrow block is about 2mm too large even with the smallest available fittings
Personally I'm waiting for dimensions on the new 3080 cards to see which pump solution is possible.
