Is your smart TV watching you right back? With the massive amount of encrypted traffic flying off modern displays, hiding telemetry is child’s play, and simply ‘opting-out’ feels pretty naive. So what can you do if you don’t want to be watched?

Custom water cooling has always been expensive, but high-end AIOs are getting pretty pricey too. So we used Bykski parts to build a full CPU and GPU custom loop for less than some premium AIOs. The question is, is going custom actually worth the extra hassle?

The AM4 platform refuses to die, spanning four generations of Zen processors. That got me thinking… Could the best upgrade you could make right now drop straight into the board that kickstarted it all back in 2017? To find out, we paired the oldest AM4 motherboard we could find with the newest AM4 CPU.

<media:description>Thanks to Hetzner for sponsoring this video! Use code ltt20 to get $20 off Hetzner products by using our link: https://htznr.li/LTT26
We traveled to Falkenstein, Germany, to tour one of Hetzner’s data centers and see how their hands-on, DIY approach helps power their infrastructure at scale. From custom-built solutions to the servers themselves, we got a behind-the-scenes look at how Hetzner does things a little differently.
