Hi,

Hack saw is fairly good at cutting straight sections of acrylic. For holes in acrylic I use the spade drills mentioned earlier. Very slowly and from both sides with a pilot hole often finished off with the dremmel sander is my favourite method. Its fairly easy to work with, just take your time.

As for cutting the case - either a hole saw for the fill ports or a dremmel in 'free-style' mode. Again slow and careful wins the day.
