NanoQ R / Mo-Ra 420: How to get 16mm tubes out of the case (No drilling, PCIe Pass-Through?)

Hi everyone,

I'm planning to cool a **NanoQ R** using an **external radiator** (likely a **Mo-Ra 420**). I intend to include both the CPU and my **Radeon RX 7900 XTX** (fitted with an **Alphacool Core Block**) in the loop. I really hope the **Core Block, including its fitting terminal and fittings**, actually fits inside the case!

# My main questions are:

1. **Is anyone running the NanoQ R or even the smaller NanoQ S with an external radiator already?** (Experience reports would be greatly appreciated!) 2. **How did you manage to route the two tubes elegantly out of the case?** I want to use **2 x 16mm** Outer Diameter **(OD)** tubes and would **prefer not to switch to smaller diameters** (pneumatic tubes). Is there a clever, visually pleasing solution for getting these thick tubes outside? 3. **Does a PCIe Slot Pass-Through fit in the NanoQ R and how should I secure it there?** My **7900 XTX** uses **two full slots for the I/O bracket**. Would such a pass-through fit into the remaining free slots without colliding with the graphics card? **And if so, how did you screw/fix the pass-through in place?** (Especially with SFF cases, securing slot covers can sometimes be tricky.)

I would **prefer not to drill holes**, and I wouldn't even know where the best, most discreet spot for that would be.

I'm grateful for any tips regarding tube routing and the slot pass-through!
