I have been happy with the PicoPSU power supplies which are tiny ATX PSU's that go up to 160 W. They take 12V input, which can be supplied by an external brick or a small 12V power supply of the sort used to supply power to lighting circuits (I use a Meanwell NES-350-12 to power 3 boards with individual PicoPSU's. For home experiments I have been using the less expensive X520-DA2 Dual copper Cat6 10 GigE boards from Intel, at about $500 per card. They are well supported in Linux. SFP+ is the way to go for fiber. Also, Netgear sells a small 8 port copper interface 10 GigE switch for < $1000. http://www.netgear.com/business/products/switches/unmanaged-plus/10g-plus-switch.aspx It's an 8-port "desktop" switch, which means unmanaged, etc. I haven't tried that. For various reasons my home machines are connected directly with each other, without a switch, but you want a switch, and this is far less pricey. I think the copper option might get you 100m of distance, but I'm not sure. All that said, if you want high end stuff, you might want to go for the X540 fiber product line and switches that seem to be $5,000 or more, plus the cost of the SFP+ cables, ... At least a factor of 10 more expensive, for better latency in the switch, fancy management features in the switch and more reach in the cabling for less electrical power. Depends on what you want. We use the higher end stuff at work.
