ICE - with a difference:

During a recent relocation to new offices the company I work for set a rule that no 'non company' (and therefore untested) electrical equipment was allowed on the premises.
I like my music so this is my answer, an old CD drive attached to some company-owned speakers and an old PC power supply.

Also, while I'm here, I'd like to say thanks ever so much to the thieving scum who boosted my car stereo, speakers & CD's.
The CD's were all scratched and old, the speakers were duff and the stereo was pissing me off anyway!
Although if I catch you, I'll kill you - I've got my priciples.
PS: The CD ontop is the album 'Mutter' by Rammstein.
