Sure, we’ve seen Power over Ethernet before – I even whipped up a simple adapter for my modded wrt54gs. This is a nice clean setup, and it’ll save you from yet another power brick. (I’ve got a power strip dedicated to the things in my tiny home data center.)
Doesn’t it strike anybody as a pretty dumb idea to hook a wire on a 50 ft. pole outside to the PSU of your computer? Perhaps they have no lightning there…

That’s how power is feed to my ISP’s Motorola Canopy equipment outside. We do get Thunderstorms, while the antenna is only 12′ high or so, my mother board’s ethernet circuity got popped twice in 6 month’s. Good thing Dell snuck in the extended warranty on me as they covered the repairs. Though I put surge protection on the ethernet line, I do try to unplug from the computer when a Tstorm rolls through. My packet radio antenna was at 35′ connected 24/7 but the radio never got burnt. Advantage of a DC grounded antenna I guess.

Note that all 4 pairs in ethernet cables are used for gigabit ethernet (1000base-T); not a huge deal, in that you can still get 100Base-T with the PoE scheme, but don’t expect all the love from your gee-whiz bang gigabit switch…

Would anything bad happen if you were to accidentally plug a regular device into one of these powered Ethernet jacks?

I wouldn’t suggest plugging in a non PoE device into a powered port. Since the jack is clearly labeled radio, it is obviously for wireless gear. PoE is pretty much what makes wireless possible. All Motorola canopy gear is Poe and that is amazingly fast. Ceragon ODU radios are also Poe, and they’re fast enough to be used as backhaul/trunks at cellular sites. That being said, I also would like to have it in the rear of my pc. I think I’ll try one that is rear mounted to power my Microtik router.

why did he run the cable back to the front?
he’d better let it run trough the pc, so it’s connected to the NIC at the back.. now its a cable just from the front to the back of the same pc!
why didn’t he inserted the power at the NIC itself? would be an even nicer hack..
(thinking of it.. someday i’ll might build such myself..)
