Computer and other devices fried... THROUGH ETHERNET

Hello, I am new here but it was the first place my mind told me to look to see what to make of this situation...
First of all, here is a list of my devices. 1 Dell Desktop PC (on surge protector), 1 Netgear router(on surge protector), 2 d-link switches(plugged straight to wall), 1 d-link print server(on surge protector), 1 HP network printer(plugged straight to wall), 1 custom built PC(on UPS), 1 cable modem / VoIP box(on surge protector), and a Slingbox(plugged straight to wall).
The custom PC is connected to a switch. The other device on that switch is my network printer. Then an ethernet cable leaves that switch, goes through a wall jack, to another switch. On that switch is the slingbox. The cable then leaves the second switch for the basement where it is connected to the wireless router, and therefore to the cable modem/VoIP box.
Yesterday a very powerful thunderstorm went through the area. I unplugged the custom built PC before the storm hit (I didn't think to un hook the other things) it was hooked up to a UPS and I unhooked it by unplugging the UPS from the wall and turning it off. A large lightning bolt hit somewhere very close to the house, but we do not know if it hit OUR house.
Both switches, the printer, the slingbox, the router, the cable modem, the UPS, and my custom PC are dead. none of them turn on or function in any way. My best guess is that the power surge traveled through the ethernet line (I have no ethernet protectors, have never thought that I would need them)

1. Would the UPS warranty cover my PC even though it was unplugged? I have read the warranty information and it is confusing, is there anyone with experience? The company is CyberPower. I also am concerned because I don't know how they would value the PC. I got many of the parts on special, but to replace it now, it would probably be over $1,000. I also don't know what they would say would need replaced (certainly the case is still ok, as well as CPU fans, etc.)
2. Where would you start in trying to fix the PC in this situation? My first thought would be the motherboard because if the ethernet port got the shock, it would fry the board first right? I am worried that it could have passed into the ram, power supply, or CPU (it is an i7, so quite expensive). The cheapest part to replace is the power supply. Like I said, the UPS is dead, so it seems like the charge came out of the computer via the AC line.

I am aware that this whole situation sounds impossible... but it is the only logical conclusion because of the devices affected. Oh, and the power never went out to anything in the house, and no light bulbs blew out. I am just curious, being an EE student, if something like this is possible and what the chances are. Or, moreso, what a more likely explanation is.
 
Your best bet is probably going to be, to submit a claim with your homeowner's/renter's insurance and let them sort things out. I lost a DSL modem, router, and two TV's earlier this year, due to lightning. Plug everything into surge protectors in the future. That's about the only advice I can really offer.
 
Holy crap, man...that's a lot of equipment to lose! :(

Have you tried all of the outlets? Probably a dumb question but I have to ask.
 
Surges coming through the cable/dsl line is very common and happens all the time. Next time get a protector that has dsl/cable line protection, just make sure that the incoming line goes through the protector before it goes out to the modem.
 
Yes that would be a nightmare. On the other hand i have one suggestion right now. A claim against the home owner policy could be in. If a bolt did hit i would also be worried about everything else in the house also. For future reference i suggest documenting what, date etc. Say an article in the newspaper to document this and a reference to date or and time you might have called about it. Proof is what ya need and witness's say other neighbors with the same problem. its all important.
 
I have a similar situation few years back, the lightening walk through the ethernet bus line, it fry all the nic cards in the line. lucky thing is only the nic cards fry, it didn't damage any thing else, and all the units are plug in an UPS and none of them are on when the lightening striked.
