Minwah:
Thanks for all the replies!

I do like the idea of MDF for the smooth finish, I don't really want a 'grain' showing if possible.

Maybe if I use MDF for the sides/front with an internal frame structure for added strength, and strong plywood inside for monitor shelf etc.

Hopefully if I prime/paint the MDF well warping shouldn't be a problem (?).  It is to be used in a house (normal room temp.).

Thanks again

Nice job SirPoonga btw.

If your going with mdf, then I would suggest laminating it.  I hate to disagree with sp but although mdf is strong, compared to plywood it's rather fragile.  I'm not saying your going to have structural problems, but lets say you bang into the corner of it with something heavy.  If it was plywood you'd get a nasty scratch in the paint and that's about it.  With mdf you might actually chip the corner off!  

Regarding your painting questions, in the short run you will be ok with just painting it, in the long run maybe not.  If you look at old arcade cabs that are made from pressed wood substances, 9 times out of 10 the bottom of the cab is damaged and rotting due to the fact that moisture is absorbed through the bottom. (This happens naturally, even in the best of environments.)  If you do paint it, take sp's example and paint it on thick. :)

Minwah:
OK thanks for the advise.

Is there any way of hiding the wood grain finish of plywood?  Maybe using filler then sanding back?  I'm not sure what this would turn out like.

JustMichael:
You might try MDO (medium density overlay).  It is often called sign board.  It can have one or both side nice and smooth ready to accept paint.

Minwah:
Thanks, I'll see if I can find somewhere that sells it nearby.
