DIY enthusiast builds custom Raspberry Pi CM5 motherboard to revive HP ProLiant N40L server

YouTuber EastMakes repurposed a 15-year-old HP ProLiant N40L micro-server by designing a custom motherboard around a Raspberry Pi Compute Module 5. Starting from the open-source Raspberry Pi I/O board schematics, he reshaped the PCB to fit the server's original chassis, added an NVMe slot, USB 3.0 ports, and Ethernet, while trimming down to a single HDMI output.

USB naming confusion means pricier flash drives often deliver real speed gains

USB 3.0's successors were renamed using confusing 'Gen' labels tied to speeds of 5, 10 or 20 Gbps, making printed USB 3.2 labels unreliable indicators of actual performance. USB-C ports add convenience but say nothing about speed, since USB-C devices can still run at USB 2.0 rates. Real-world tests, like Kingston's DataTraveler Max hitting up to 1,000 MB/s versus Samsung's Fit Plus write speeds of just 58.4 MB/s, show huge gaps hidden behind similar branding.
