I'm looking for a small PC. I see these mini PCs and HTPCs now and then, but don't know much about them. What I'm looking to do is get a PC I can set up at home and leave running on my network so I can log into it remotely. I'm going to be abroad during holiday sales time and I want to be able to log in remotely to shop online (afraid my orders will get cancelled if buying from foreign IPs). Ideally, I'd be able to leave this thing on for months. Practically, I know that might be tough. I don't need anything resource intensive - literally just web browsing. Any suggestions as to where my budget should be or if this is realistic?
