I got one a few years ago when i was toying with the idea of going ITX.
It's in my mid tower now with extension cables and it has been running perfect.
You get so much more room under the PSU shroud and having extensions on the short cables take up no extra space round the back of the case (except for the 24 pin connector).
Only drawback really is the 7 year warranty, not sure why it was not at least 10 years for such a premium PSU.
