*gnarf* … it seems I wrote this 2 months ago and never published it to the blog …

Used hardware:
5x Nvidia NVS 440 dual gpu, dual head -> 2xDMS-59 -> 2xDVI
2 A$$rock X79 Extreme 7 mainboards never buy Asrock. I mean it.
1 P9X79_WS mainboard
1 i7 3930k CPU (because I wanted it … not because it was necessary)
1 SilenX EFZ-120HA5
1 Enermax Liberty ELT500AWT 80Plus
4x 4GB (Quad-kit) Mushkin Redline DDR3 1866MHz
2x Noctua NF-P12 PWM silent fans

20 resuscitated Samsung 940B/BF/T screens
20 DVI-cables from 1.5m to 5m, 20 VESA mounts, 4×5-port socket ports

For now:

And a video … from a few weeks back

Build log/pictures and details will follow.

P.S.: And then there’s this *jealousy dripping out of my eyes* … for ~20k$.
(and it doesn’t even give you any trouble with MS OS gpu limits since there are only 4 driving 24 screens)
