there will no doubt be some kind of coffee table that is hollow inside with glass top or even one with a glass top that you could maybe install your own glass panes or solid panes into the sides so it cant be accessed.
if you're feeling flush check out Geeknson - they have a lovely vaulted coffee table that would do it justice!
Thanks chaps.
The Geeknson tables look nice, but not quite what I am after and definitely too expensive.
It is tricky because we use the coffee table quite a lot but we live in a flat so space is somewhat restricted.
I wasn't even sure that we could afford the kit, or have the space for it, but the missus wanted it so badly that she bought it without consulting me.
So, the reason I asked for a display case is that we have a table it can sit on, but it is rather out of the way and it would be nice to display it more prominently. Still, if a suitable table can't be found then it is the only other option I can think of. That is unless someone has figured out a way to wall mount it?
