Similar to purchasing a cell phone on contract, I want to give miners the opportunity to land a larger amount of hashpower with a smaller amount of up front capital.  So for example, you could put down a 30 - 40% deposit on a half rack hosted.  This would put your hardware in my datacenter, where it would mine-out the remaining amount owed on the order.  Of course you will pay more for the hardware financing it this way and it would require hosting which adds a revenue share (5% - 8%).  Once the gear is paid off you could take delivery, or leave it in hosting mode.
