Id upgrade to mikrotik since its a significant upgrade from what there is.Why would you "upgrade" to Mikrotik, from what I read their "Network OS" (Router OS) is not that great.
im fine with using and paying for the power, but i will still be renting out majority of the basement so it cant be ear deafening through the 2 walls seperating the racks from the appartment.It didn't seem you cared about Power Consumption at all.
That is why im usualy avoiding 1U, the jump up to 2U fans helps so much on the noise.
