Surplus 10G switches at good prices are likely to be sfp+ and not 10g-baseT at this point in time, too. DAC for same rack is a no brainer at that point. To the rest of your house depends on what you've got in the wall and how easy it is to put new stuff, I guess. I'm running 10G-baseT between my two network cabinets, because there's no economical way to pull anything else, and there's no reason to go for more than 1g other than fun.
