Ah yes, SGI. These guys knew how to build computers.
Back in the day I used to run a lab full of SGI machines, including an Onyx which was a rack similar to the one in the video. Those machines were joy to maintain, rugged, super reliable and easy to repair (well, swap components). Everything on connectors, attached directly to a backplane. Not like PCs with cables everywhere, even in servers. Upgrading a CPU on an SGI machine was 10 minute job, including the motherboard removal.
Probably the only company with somewhat comparable build quality used to be Sun, on some of their servers.
