Question about Sharkoon QB One

Yes, you can get the lid (no longer closed). If you do get the lid closed, the hoses will obstruct the fans. 240mm are not recommended

According to the description, a 240 WaKü is basically possible, but you must pay attention to the height of the radiator and the fan. 5 cm is probably the maximum. Unfortunately, I bought a be quiet! Dark Rock TF for the set, which definitely doesn't fit. It bends the GraKa and the inner RAM bar outwards. So I had to buy a new one. The new one is a NZXT Kraken M22 120 WaKü. This should fit in, but was unfortunately not on offer at Digitec. :-(
