I was going to use an old Dell i3... however I am thinking of using one of my old laptops. Both have their merits. The laptop has a build in monitor... however I do not need the monitor once the O/S is installed. I then use SSH. I'm thinking the Dell mini tower has a faster bus and memory. And it has 8GB of RAM vs 4GB of RAM on the Laptop. I'm guessing the faster bus and RAM will make a difference. They both have 2 cores and 4 threads. Both CPUs benchmark the same and they have the exact same SSD. I'm thinking the mini tower is better. I do not think I will ever use 8GB of RAM on a home web server. Given what everyone is saying, the amount of power used is somewhat dependent on demand. Low demand = low power usage. > The Raspberry Pi Zero W costs $10, and has these features: > > • 1GHz, single-core CPU > > • 512MB RAM > > • 802.11 b/g/n wireless LAN > > • Bluetooth 4.1 > > • Bluetooth Low Energy (BLE) > > • Mini HDMI and USB On-The-Go ports > > • Micro USB power > > • HAT-compatible 40-pin header > > • Composite video and reset headers > > • CSI camera connector > > It consumes 120-170 mA (but can source over 1A to USB), so can run off > of a USB battery pack if needed. > > This puppy has more power and features than that mini-ITX machine I > had! > > It comes with a ready-to-run Linux on an SD card and fits into a box > about the size of a pack of cigarettes.
