Haha. well, it is not a few hundred dollars… 450 euros is about 600 Canadian not including shipping and HST… so about 750 dollars CAN. I have enough spare water cooling parts to make it work… or use the aquacomputer ultitube d5 200 pro leak shield reservoir… another 329 euros… (best solution, everything you need, and safety too.. just need a wall wart… fittings, and tubing)…
A larger problem is how do you fit this quantum ps5 monoblock inside your PS5 case, and hang the pump/reservoir outside the case.
