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.
There's worse ideas than asking on serverfault chat, we're fully of options and ideas on there.
