this scheme needs some qualification. For example, what if I pay for three months upfront and then, after a month or two, have to do a RMA back to Spondoolies. What would happen in this case?
Our policy is to charge 50% for reserving the space for you whether or not you actually use it, and 50% for actually using the power. If you buy 3 months of hosting and tell us your machine will arrive on September 20th, but you had the bad luck to have purchased from (e.g.) Black Arrow, and they tell you (and you tell us) "next week" until November 20th (2 months later), then you would have 2 months of hosting left.
We are ordering spare PSUs for SP10s and SP30s, so if the issue is PSU-related, we'll swap your PSU(s) out with our spares and RMA the faulty ones, and have you up and running in about a day. If it's an issue with the miner itself, then you'll have to wait for the RMA to return, and will only pay 50% hosting fees for the duration, unless I take pity on you and waive the 50% space reservation charge.
