The recently announced Steam Deck was seen by many as the ultimate mobile gaming PC but Valve warned against opening the device to see its inside.

Trying to do a personal upgrade by doing a personal rig is a common practice among PC owners, however, Steam released a new video on Wednesday that says otherwise.

In the video, a tech expert could be seen opening the Steam Deck while also explaining the risk of DIY rigging to modify the internal components of the device.

“In one way, this is a ‘how-to’ video. But in another way, it’s a ‘why you really shouldn’t do this’ video,” Valve says in the clip. “Opening up and replacing parts might mess things up, like profoundly.”

Even though Valve acknowledged the fact that every owner of the Steam Deck has the ultimate right to open up the device to see its internal components, it’s just stating the risk of opening it due to the components used to power up the device.

This is a pre-arrival video which the company is using to warn its potential buyers before they eventually lay their hands on the device later on this year as shipping starts in December.

Another reason not to pry open the Steam Deck is the fact that it could weaken the device’s durability and drop resistance and unless you’re Zack from JerryRigEverything, you may want to keep your hands off.

“There’s no way to avoid this,” the video says. “So just know that the structural integrity of your Deck will be lessened somewhat by doing any of this.” The company also warns damaging the battery could result in the whole system catching fire later.   

Valve told IGN that it would be a good idea if future owners of the Steam Deck try not to replace the device’s M.2 NVME SSD storage drive inside the device even though it’s can literally be replaced.

To keep the device safe, the company warned that an off-the-shelf NVME SSD storage could lead to overheating and battery problems due to the storage module potentially drawing too much power.

The SSD is also located close to the Steam Deck’s wireless module. The default SSD that comes with the gaming handheld was “specifically chosen and tested to not interfere with Wi-Fi and Bluetooth,” the video says. Hence, adding a third-party SSD drive could generate too much electromagnetic interference and muck things up. In addition, an off-the-shelf drive might “mechanically interfere” with the other components located on the motherboard. 

The company further explains that there are differences between the SSD storage inside the Steam Deck compared to your typical 2280 M.2 NVME storage drive.

However, in case you want to modify the device or just repair it, Valve provided a couple of useful information on what you’ll likely encounter and what to avoid at all costs when trying to open the device.

The company further announced its plans on announcing source replacement parts to the Steam Deck in the very near future and those include thumbsticks as well as SSD storage.

There is also a possibility that it may offer repair service as well but this isn’t stated exclusively in the video.
