Here is my current setup. Though not built intentionally for day trading, it's getting the job done.
PC - Wonderful little computer for productivity, media consumption, and even light gaming. The machine is barely audible from 2 feet away with the silent Noctua fan. It literally fits in the palm of my hand.
ASRock DeskMini (Barebones)
Intel i7-7700
Integrated Intel HD630 Graphics (no video card!)
32GB DDR4 RAM
Samsung 960 EVO M.2 250GB NVME Drive
Crucial MX300 525GB SATA SSD
1TB Samsung Hard Drive
Noctua NH9-Li CPU Cooler
All that performance is crammed into a package that is smaller than Andrew's book!
Monitors - Two ultrawides really limits the cable clutter/additional hardware required for a multiple monitor setup. However, there is some ergonomic drawback as the overall height requires quite a bit of vertical neck movement.
LG 34UM88-P 34" Flat Ultrawide (top)
LG 34UC88 34" Curved Ultrawide (bottom)
Mounted to a Vivo STAND-V002T Dual Monitor Vertical Desk Mount
Desktop/DAS Layout - I am able to fit 10 montages in DAS which includes:
8 x Stations with 5 min chart, L2, Time/Sales
2 x Stations with 1 min chart, 5 min chart, L2 Time/Sales
Central "hub" showing Market Time, Top List, Open Positions, Open Orders, Watch List, Windows Calculator
Bear Bull Traders Chat and Andrew's Trade Idea Scanner
Most of the time I am watching 5-6 stocks and just keep some low floats up top to avoid any FOMO!
Keyboard - MechanicalEagle Z88 RGB Backlit. Fully customizable down to each individual key colour. I use green for long hotkeys, and red for short.
Desk - Ikea Malm White
Chair - Vertagear S-Line SL2000. Very comfortable for extended sitting. Includes a lumbar cushion and neck/head pillow. I may consider getting a standing desk in the future.
Miscellaneous
Glorious Extended Gaming Mouse Mat - keeps the white desk nice and clean
ALED LIGHT 5050 LED Strip for ambient backlighting behind desk/screens
