Alright let's see pictures of your super nice rack-mounted, professionally installed labs. I'll start ๐

Here's my beautiful unemployed-for-too-long-have-no-money-dont-care-about-looks lab :)
Hey it's more than good enough to run all this ยฏ_(ใ)_/ยฏ
Easy to get these days actually, with 10gbit sfp+ and 8x 2.5gbit, managed switches. About $60.
But my actual argument was that your 48 port switch eats electricity like crazy. That aint a cheap switch at all.
The only brand new, 10gbe managed switches that I can find for less than 60 bucks are off-brand chinese junk. No thank you.
As far as electricity cost goes? After doing that math, it might cost me a dollar fifty a year to use. That machine sitting on the bottom is a much bigger chunk than the switch itself, as it has 6 7200rpm SAS drives in it. Plus it's a Xeon E3 CPU.
Those drives, each, use as much electricity as that switch does, even before considering the CPU itself.
