My dad has a small business and he has always have problems with his server. He has roughly 15 other computers using it. The last company to upgrade it basically charged him 5k and gave him some storage upgrades
I'd like to figure out a build for him.
But have no clue what to select except I really think he needs RAID 5. If his system is down he has zero production.
What would you recommend with total server cost around 2-3k, what MOBO/CPU, RAM, etc?
