Make sure your recycle bin is emptied, that's usually what takes up a lot of space for me Also run CCleaner, it might be able to free up a bit of space as well

Folding is really picky about overclocks, and it stresses systems in a different way to standard benchmarks. The best thing to do would be to remove the overclock(s) and see if it crashes then Also 1.6V is pretty excessive IMO, I'd turn that down if I were you

Nobody really knows apart from Microsoft themselves, but some common reasons that are speculated are Microsoft wanted to make sure that it wasn't closely linked to Windows 8 As @Kevin_Walter said, they counted Win8.1 as Windows 9 Apple called their operating system OS X and it's worked out for them, so Microsoft copied them because 7 8 9?

Could you post the minecraft crash log (if there is one)? It would help us a lot if you could It's probably located in %appdata%/.minecraft/crash-reports

Yes, this is possible The guide you linked shows you how to do 3 things: Install and set up FreeNAS, Port forward your router, and up a dynamic DNS service Install FreeNAS I assume you're able to do this part, but here's a video anyway: (The main video starts at 0:47) Port forwarding If you've never port forwarded a router, this can seem complicated at first, but it really isn't once you get the hang of it. Port forwarding allows you to connect to your NAS whenever you're not connected to your home network. http://portforward.com/english/routers/port_forwarding/ has guides for most routers, and if you can't find the exact model you have, try something similar as the process will probably be similar within the same manufacturer. Note: There does seem to be an ad that pops up every now and again for a software utility that can port forward your router automatically, just close it. It really is simple to do it manually Dynamic DNS This just makes it easier to remember your IP address (instead of typing in something like 281.232.281.656 you could just have is be a URL like example.no-ip.org or example1.dyndns.org depending on the provider you go with.) I use noip, and here's a guide for it http://www.noip.com/support/knowledgebase/getting-started-with-no-ip-com/ although most services will have a similar setup process Since this will be visible from the internet, you'll want to choose a strong password (I hope this is obvious, or at best just slipped to the back of your mind) Also, you might want to consider what @braneopbru has said, owncloud is pretty simple to set up and is pretty secure I hope I haven't left too much out of this post, and if you need any help just PM me, and I'll try my best

No, instead of you constantly transmitting data your progress is packaged up into a finished work unit and then is uploaded to the F@H servers. Whenever the WU can't be uploaded, the program just retries until it is successful (I think) The only time you really need your PC to be connected to the internet is when you're downloading and uploading WUs

yeah I know, just being specific to that post

I got roughly 65-70K PPD with my R9 270, so expect similar results
