Lack of a CD rom is really no big deal - I have a netbook, and it's never caused me any problems, unless I have to install an OS again

- but external USB CD rom drives are handy to have around, just in case. Plus, I've found that CD drives are becomming less and less reliable - so having a spare that you can just plug into anything is a good idea.
I think that your right about acrylic - plus if you use tubes for the round edges, you can easily hide any ugly joins. Maybe a metal mesh for the front and back, easy to cut, bend and fit, and good for air flow.
