I'm a big fan of modifying stuff, no matter what it is, it can always be changed to be unique ^^
When I moved out from my parents I got an old white table with tiles in the center, painted it, smashed the tiles and replaced it with a box and a glass-top.

Then I went on and restored and modified a couple of speakers I got from my dad (from the early 80's the sound is to good to be tossed away).
From the start they where dark gray with a wood pattern and with black cloth in front. Now painted in a highgloss black and with white fabric in front.

And when modifying isn't enough, you got to design and build something from scratch, right?
Built in MDF and then spray painted with a highgloss black color. Inside there was a PS2 and a Nintendo 8-Bit, cables where run through the base and beneath the sofas, so now cables where visible from the games to the TV.

And yes I've built an arcade cab with two hacked retro amiga-joysticks and a hacked keyboard, but the cab looks terrible so I won't showcase it.
Right now I'm in the process of finishing the new shell for my HTPC (made in 2mm steel, heavy

).
