Yep, i agree with everybody here.
I don't have an OCD when it comes to PCs, but i do like to keep my things clean and neat.
My Music folder arranged by artists, then albums, then songs with their respective tags and they're all the same bitrate.
My Images folder arranged by subject or occasion with their names by "Img XXX" respectively.
My Documents folder arranged by subject (in case of my university paperworks) i have it arranged by semester, course and documents.
When i uninstall a program/app i like to make sure i completely deleted it. I'm really picky when it comes to computers.
I defrag my HDDs once a week.
I have a separate HDD for all my data and stuff like that.
Geezus, i've just described an OCD'er. LOL
