If you are talking about srlf-build, there is reason to avoid that for people who can afford. It is called warranty. Hardware rig like this goes through testing and the support package usually is pretty good. I don't have first-hand experience, but I know Oracle would send engineers onsite to troubleshoot if required. Unless you are ready to tackle the build, the testing, and the support of the hardware rig, you want to avoid. You don't have to be Dropbox or Netflix (I don't believe they build custom servers like facebook and Google does, perhaps they buy from other vendors or from opencompute project).
