@d6 Feast your eyes on this. All salvaged.

Spent more on the rails, RAM, and disk caddies, than on the machines.

The two DAS unit cost me $12 each.

Over the years, aside from these, I found at least four computers on the side of the road. Probably been through about 50 computers no one else wanted. Sometimes had to take apart three to build one.

I did have to buy a Windows laptop for school. Work does provide new equipment they own. Otherwise, I only used salvaged or surplus items.

Bought one ruggedized military computer. Bought another ruggedized one from the police. Universities have proven to be a good source of supply.

Every last one has had years of capability left in it. Yes, some had to be parted out, but often my recovery rate is 60%.

It's amazing what people are throwing in the garbage. Like, half their wealth.
