Generally, motherboards that have non-standard backplate configuration include the matching backplate with the board. Every board I've bought has been that way... (YMMV)
I agree with iz there... the mother board should've come with a backplate... if it was missing you should try and contact newegg... maybe they'll send you a new one
First off, the board isn't here yet, so it may come with a backplate.
A new board will come with a backplate, but this was a refurb. newegg says they won't provide any missing parts for refurbs, and not to expect anything.
I could probably get shuttle to send me one, but (not to sound cheap, well, ok, I don't care if I sound cheap). The board was $23 including shipping. If I have to spend $5 shipping on the backplate, it's not such a good deal.
So I'll probably go the posterboard route. I was mainly just wondering if this was the best thing to use (price/convenience/functionality) wise, or if there was something else you would recommend?
