The desk is fully adjustable and designed to hold 9 or more monitors. The monitors are positioned on a shelf that can be manually adjusted to be closer or farther away from the user. The keyboard surface and monitor surface can be individually height adjusted using electric actuators and have enough range to be used as a sitting or standing desk.
The desk is made from Solid Oak wood.
I use two sets of actuators from Progressive Automations for the up and down movement. For the keyboard desk I use the FLT-03-2-2 Table Lift Set which starts at 22 inches and extends out to 38 inches. For the desk the monitors are on I use a 3-step Table Lift Set also from Progressive Automations that starts at 16 inches and goes up to 32 inches. They no longer sell the 3 step model as a set. Both of the sets came with a controller that allows you to adjust the height manually as well as set four positions in memory for one touch adjustments.
The monitor stand I'm using is from EasyMountLCD and is a Deluxe Hex LCD Monitor Stand Desktop Clamp. It holds six monitors that can be up to 28". I use the top row to mount my speakers with a 100x100 mm piece of oak screwed to the VESA mount. The oak piece has a screw to mount the speaker along with a small hole for the wire to fit through.
Everything is powered by one PC. Two NVIDIA Geforce 770s in SLI power the main display. A Geforce 650 powers 4 displays, and the Intel i7-4770k HD 4600 powers two displays.
The top center display is an Asus VG248QE 144hz 1ms with the G-SYNC kit modification. The other six displays are ViewSonic V3D245, VP2250wb, VX2233wm, VX2439, VX922, and VX2453.
The speakers are a combination of two Logitech sets. I'm using the satellites from the Z906 and the subwoofer and control unit from the Z-5500.
