Moving kit
Nothing to do with expensive purchases, but I once had a fairly hefty rack-mounted (6 or 8U) UPS delivered to my 1st floor server room. 3 guys arrived and very slowly humped the thing up the stairs, cursing about the weight all the time, and eventually got it into the server room. Then they waited to see what I would do with this overweight monster...
...the looks on their faces, when I removed the batteries and gently lifted the chassis into the rack, were a sight to behold.
