I am researching how to build my first computer and was wondering if any one has advice on a motherboard and video cards. I want to build a computer with multi-monitor support. And by multi-monitor support i mean 16 to 24 monitors. I plan on starting off with 4 to 8 monitors and increasing the video cards as needed. Is there a rackmount motherboard that has many slots for video cards that i can use. I would prefer just a regular mother board. Are the usb to dual hdmi adapters worth buying. Or will a dvi splitter work. Thanks for any advice.
