How often do you need cable extensions?

[MKSanic]

How often do you find yourselves with too short a cable and need cable extensions?(like your cable cant reach all the way across)

[Kanna]

When building pc's only one time and that was a fan cable that was not meant for the chassis, if we are talking general some appliances keyboard speakers and such may have needed extensions

One of the most common extensions I use is USB for my mouse/keyboards. I also have a USB and Display port extensions on my VR headset to give me more room.

Unless using a massive case like a Corsair 1000D or some CaseLabs (R.I.P.) models, or trying to reuse an OEM power supply, never.

When using cheap PSU's (Im looking at you EPS connector)

In the PCs themselves, as mentioned above some EPS connections from PSU are too short to go around the back of the motherboard tray. Almost always I use SATA power extensions, as the gaps between SATA power connectors on the cables can be quite short, so use an extension to reach my fan hub for example, instead of using 2 SATA leads.
