That's not such a monster. A week ago I had a custom-built computer in a "Rain" enclosure that must have measured a meter by a meter and had a built-in carrying handle to lug it around with. That sucker weighted about 90 pounds, had dual Xeons, 50GB of memory, 4 1TB hard drives, an Intel WorksationS5520SC motherboard, and what looked to be a 1200 watt power supply. I was asked to clear the BIOS password after its owner died. After doing that, I couldn't get it running because start-up repair repeatedly failed and the system kept shutting down every few seconds. Rather than replace the heat sink compound on those Xeons, I asked the customer to take it to another shop that does a lot of servers; I'm too old to be wrestling with beasts like that.
