the cables on my floor get regularly hauled out and reconnected and although it looks tangled they are discrete bundles on top of each other, or at least they stay that way for about a day.
the blue/purple pc in the bottom pic is for pic programming (that's what's sitting on top of it), it is connected to the tv and the rightmost of my 3 monitors via a long vga cable (the monnitor has dvi and vga so i use dvi to my main pc, there's a usb keyboard on the floor in that mess of cables connected to the blue pc too (i would use a kvm switch except the ps2 ports are fried and usb to ps2 adapters are a bit dodgy.
the dell isn't connected to anything and doesn't currently even have a hdd, but i have ide to cf adapters that i plan to use with it which make cf disk appaer like a hdd for booting and things, might play with kernel development once school's out.
