I'd highly suggest a Xentera GT AGP video card, they make one with 4 DVI outputs on one card. It uses dual ATI Radeon 9000 chips (each chip can do 2 monitors), so the drivers are pretty standard and the card works well. The card has a street price of about $600 right now.

As far as monitors, that's a personal choice, I love my Samsung Syncmaster 213Ts. Most LCD monitors have a wall mount option, If you did that you could easily mount 4 of them to the wall.

Without the PC, you're looking a 2 to 3k if you use LCD/TFT monitors.
