It is not about being "brave" but about being informed. As of 2018 you can probably call "brave" everyone who uses any modern computer. However this machine was purchased in 2012. Consider what was known then and what is known now. The motherboard ASUS P8Z77-V does not support ECC memory. Still we needed and paid for 32GB of RAM, not for 31.5. -- xxxxxx
