I have been charged so much money from them. I sold a PS3 that I won in a contest and had to re-ist because a scammer bought it and I had to revoke. I relisted about 4-5 times and now eBay thinks I sold $1200 in merchandise. Also PayPal freezes peoples accounts for no reason, even when they can have $10,000+ in them.
Could possibly be dead until you get a new motherboard. You could try booting something like Ubuntu from a USB drive and see if it works there, that will rule out if it is your OS or your hardware.
If it works w/o the extension, it's pretty safe to say it's broken. You might be able to return it, most USB extensions are the same so when you get a new one get the cheapest one.
I think the build looks good to me then. I know that a lot of people get coolers like the H100i and don't even enter the BIOS. Input from some other users would be good, better to get an opinion from several people.
A couple of smaller reasons, but I just mostly think it's a pretty cool country. Also lots of internet freedom. That wouldn't really justify moving itself, but it would be cool to maybe have a second home there. The views would be amazing, too.
You can also pick up a G700 for around $60-$70. The G700s only has a little nicer clicks and a rubber coating, I own both and it may not be worth the extra money. If you want to save a little, the G700 is a great option.
