Mini-ITX shows you how they integrated a VIA EPIA mini-ITX motherboard into a 15" LCD display:
I was always charmed by the VIA EPIA Mini-ITX boards, so when I came across one on eBay I just couldn't resist. It was an impulse buy. When I got it I didn't really have a use for it. Then my internet provider upgraded my bandwidth and so I needed a second PC for light surfing and downloading. I wanted something small and energy efficient, so the EPIA board came back into favour. Energy efficiency was going to be easy, that's what these boards are designed for. The board is small and would require a little modding (always fun).
My brother in law has an iMac and darn do these look beautiful. This was my inspiration. I considering modding a CRT monitor to hold the PC, but it would have been too big and clumsy. Considering the room you have in a CRT it didn't seem to much of a challenge either.
