I've been running RaspBMC since I got my first Pi (first-gen Model B) and it is a great media center, at least if your media is encoded with the codec(s) it has hardware support for and you spend the $3 or whatever for the licence code. I now have a B+doing the job for the extra USB ports (wifi dongle, Logitech K400 dongle, 2 USB disks) and beefier power. It has no problems with full HD video at all.
The one thing I have noticed is that you really need to get a good, fast (micro)SD for the system, something like a 30MB/s Sandisk Ultra. It makes no difference to the video playback, but the UI is much more responsive.
fdupes is excellent and I second that (please mod the parent up!)
The only drawback to fdupes is that the files must be identical, so two identical images but where one has some additional metadata e.g. inside the EXIF won't be deduplicated.
That model isn't a climate model at all, it's an energy economy model, as are the models it replaces. This has nothing at all to do with the availability (or otherwise) of climate models
