Hardware

Hardware needed:

• Raspberry Pi 4, 4GB RAM
• 16GB micro SD card
• 3A USB-C power supply
• 500GB USB SSD drive
• ethernet cable
• cooling case

RPi	4GB of memory is a must, geth won't work with 1 or 2 gigs
SD card	16GB or more
Power supply	it needs to have USB-C and amperage 3A or more
USB SSD drive	500GB recommended. For example Samsung Portable T5. Connect your drive to one of the "blue" ports (these are USB3):
Ethernet cable	for performance reasons don't use wifi
Cooling case	if noise is not a problem - go for an active cooling case (with a fan), otherwise get a full aluminum case (aliexpress: raspberry pi 4 case aluminum). I'm using the one on the left but if I had to get one again - I'd choose the other one (and disconnect the fans when cpu-intensive tasks are finished). When the Pi4 heats up beyond 80°C (176°F), the CPU is throttled to reduce the temperature. If the temperature goes up beyond 85, the GPU will be throttled as well. (source)
