Here is my set-up, but it won't be very helpful, I'm afraid. As you can see it involves two old 20" Apple Cinema Displays -- but for me this is the perfect set-up.
Specs: mini, two 20" Cinema Displays, iSight, LaCie DVD burner, LaCie CD burner, 1Tb Western Digital external hard drive, 250 gig LaCie external hard drive, 250 MicroNet external hard drive, Soundsticks, Epson R1800 and RX580 printers, Epson 3200 scanner, iPhone, Earthdesk for desktop, wired keyboard (I prefer one with a number pad) and a Mighty Mouse.
Some of this stuff is almost ten years old but is in fine condition (which is more than I can say for myself). The bottle of Pinot Grigio is only a couple years old and was not strategically placed, believe it or not -- it is Saturday evening, after all.
