I bought a Raspberry Pi before, left it powered on for half a year, and then it just up and died for no reason… Once it died I had no idea how to fix it, and I don’t think it was covered by any warranty, so it just sat there collecting dust. Recently, for certain reasons, I needed a small computer to use as a server. Originally I was thinking of buying one of those recycled thin clients, but with electronics you always buy new rather than old. The server didn’t need high performance anyway, so I just went with the newer Raspberry Pi. The latest Raspberry Pi: Raspberry Pi 3 Model B+ . Compared with the previous version, the CPU is improved and the network card performance is expanded—it’s now a gigabit NIC! Sure, it’s still routed through the USB bus, but that’s better than not having it, right? The price was fairly low when I got it, and Taobao has all sorts of cheap bundles—basically a simple case and a simple heatsink, but that’s about enough. Actually, when I bought the Raspberry Pi 3, I somehow ended up contacting the Chinese general distributor. This time the distributor just ignored me, saying they don’t accept retail and telling me to find their sub-sellers on Taobao, so I had no choice but to buy on Taobao. It even came with a case that looked like a big gift pack.
