I had good luck with SuSE and OpenSUSE running KDE 3, but KDE4 was a disaster. Right away, things failed, like being unable to write to an iPod 5 or below. As upgrades came along, things got worse--spurious console errors, UI elements not drawing, etc. The final straw was KDE4's "semantic search technology" which never worked on any machine I tried, and which I blame for rendering 12+ years of email totally unsearchable other than by find and grep in a terminal session (maybe Nepomuk was not it; maybe it was other lousy bit of software; the results were that all attempts to index mail died).
When my home Dell box died, I took is as a sign. I'd never liked Gnome, so after 15 years of Linux as my personal OS and longer as my work OS, I went back to Mac. There are things I miss about Linux, but with my Macs stuff just works. I certainly don't miss KDE. And my mail is once again searchable.
You will have many recoverable tape errors.
