Hello. I am planning to build a computer for server VM uses. I will be simultaneously running 6-7 VMs at once. Therefore, I need a computer with a lot of and fast RAM. I have already tested that 16 GB RAM is not enough. SSD required for heavy read and writes too. CPU will be an afterthought since my tasks will not be really CPU-intensive. I DO NOT NEED GPU. Please recommend the best components for this type of build.
