I like my current hardware. Runs great.
Ditto. All of my important home office stuff is on an XP machine, now off the internet. I just got a refurbed PC on which I have Mint 16 (alongside Win 7 Pro which isn't being used). A KVM switch lets me go back and forth as needed.
Neato.
I have an old 8x Compaq rack mount KVM (that somehow handles 1920x1080 analog) that cascades through a 4x and another 4x to a buncha old 486's.
