The pc does not have back compartment, nor anyway to attack the cable to. What I am thinking right now is to hot glue some zip ties to the centre gap between HDD and mb. And then zip ties the cable to the zip tie, so it runs down the centre of the pc cleanly and branches out to its destination like a upside-down tree.
The wires are kind of short to do much here. I’d just try and make sure they’re all tied up in one bundle
What I was about to say: wires seem way too short to do much. Tying them together would be my choice too.
Also, I’m really not an expert but I’m also not sure this machine needs that much of cable management for improving airflow as there must not be that much to begin with? I see the two fans at the bottom but where is the ventilation in the top of the case? So, I’m not sure much air would have to pass through the bundle of cables.
Would bundling them potentially be a source of unwanted heat? Possibly not, I’ve no idea! 😁
