Sorry to hear about your misfortune, boohbah. These type of things always appear to happen at the most unopportune moments.
The upside is, you'll have a new toy to play with. From experience, i reckon putting your old harddrive into your new comp, should not be difficult, especially if it happens to be a sata drive. If ide, just need a different cable, etc.
Hope the 30th comes along quick for you.
