Music can be a great tool for self regulation. Classical piano can be calming and help your concentration. If you are on a roll and just need steam to keep going listen to Jazz or Jungle. I find anything with lyrics too distracting - at least if they're in English. Sounds like an oppressive work environment though - I doubt the management is any good if they've got shit like that coming out there mouths

Let me tell you what you will discover at the end of this exercise: Computers are a LOT faster today than they were 15 years ago. Moores law is transistor density doubles every 18 months or so which translates into a 1/2 price drop or 2x the speed or power. This exponential progression is roughly equal to a 10x speed increase or 90% price drop every 5 years. Applying that to a machine that is 15 years old. That's 5+5+5 which meant it's about 1/1000 as powerful or valuable as todays machines. 1000x is a bit too much but think about any other stat of the machine... 28M x100 = 2.8GB (a decent amount of RAM for a machine these days) 750MB x 100 = 75Gb (small by todays standards) 1.44Mb drive vs Flashdrive which people literally give away these days. (floppys died for a reason - I can only assume you are too young to have experienced the frustration of losing an important document to some grit in your pocket) Trust me - it's not worth it. (I had to resurrect a few machines myself to come to this realization) At least start with a better machine - I'm sure you could get something better for free, put a wanted ad on craigslist or look at surplus auctions (schools sell old machines by the lot)
