Here is a picture of the desk that I made for her. Its a Fully frame with a 72 wide Sapele butcherblock top. The top was 39" wide. I ripped 9" off and placed it op top as a riser using 3 piece sof some left over hardwood. Sanded to 320 grid and finished with mineral oil.
I also made a grove in the underside of the riser to hold an LED strip light over the entire with of the desk (warm white dimmable).
The iMac is connected with Cat6 ethernet. Desk phone is also hardwires and receives power via POE. Entire desk has a APC backup power supply.
