Three deliveries today, the 16gb CF cards (small box), the 12 4tb hard drives (medium sized box, fragile) and the books from Amazon (big box, quite heavy, maybe 20 pounds).
I don't know who delivered the CF cards, someone else answered the door, but all was well. UPS delivered the 4tb hard drives, he was very careful with it, got a signature, and went on his merry way. Well done Bluepoint, delivery next day, perfect!
The Amazon delivery was dropped over the gate (a height of about four feet) onto wet grass. The rather flimsy box split open and the books spilled out. I noticed them a while later - fortunately, it hadn't rained. The driver didn't ring the bell, because we were in all morning. Books aren't harmed by a four foot drop, but other things that one can buy from Amazon can be fragile.
I made a severe complaint to Amazon, who assured me that good delivery was a high priority.
I've built up the two replacement computers, with six 4tb drives in each, loaded Linux Fedora core 17, and I'm now loading terabytes of data onto them. That'll take a few days, then I can go install them at Cheltenham.
I'm also going to try to repair the computer that died there. It's just stone dead; I suspect it's a failed power supply, so I'll take a few with me, and maybe I can repair it on-site. Another computer has a duff hard drive, so I'll just swap it out for one of these nifty 4tb drives.
