What is the right site to ask about hardware advice? In particular, I realize serverfault would be right for big iron, but what about netbooks?
If by 'hardware advice' you mean $product recommendations then there probably isn't anywhere as shopping questions are generally off topic.
If you are after general troubleshooting advice etc then for netbooks Superuser is probably your best bet.
Caveat: If you're asking about troubleshooting advice for a Mac product you may want to try Ask Different– voretaq7Jul 11, 2012 at 17:49
There's worse ideas than asking on serverfault chat, we're fully of options and ideas on there.
1Jeff Atwood himself set up a chat room for product recommendations of routers so this seems a likely place– RqomeyJul 11, 2012 at 8:38
