I have two 4Bs with 8GB. I bought the first of the kit from another reputable vendor but it didn't boot reliably and then it wouldn't boot at all. I thought he was dead, so with a heavy heart and light budget I bought another one. I changed it in the kit and after many errors it started and then worked for days. I bought two of these ArgonOne cases/power supplies and installed both 4Bs in them. They loaded every time and everything is fine. I find that 8GB of RAM increases inrush current beyond what the official Raspberry Pi 3 amp wall warts and 5.1V 3.5A block that comes with my kit can provide. Block Argon 5.25V 3.5A, always works. Now for the case itself: it's well designed, fairly durable, dissipates heat, and has all ports on the back, which is very neat. There is a window on the front of the base that shows the red and green LEDs so you can get some info on how the Pi works. I put heatsinks on one of my Pis so I had to take them off to press the case against the chip cases and dissipate the heat. There is also a fan. Relax! By updating the bootloader on both boards I don't use the SD card; They boot from SSDs (64-bit Ubuntu OS and 32-bit RasPi OS). They're both currently connected to my TESmart KVM switch (also from Revain) along with my main computer, so they all use my trackball, keyboard and 4K monitor. I'm a poor but happy tourist.
