We only need to have 25 and we can place the order. The hosts are the bulk of the cost, so once we get enough buyers to pay for the hosts order we can order them.
Once the hosts are ordered and the heat sinks are ready, I can front the cost of the heat sinks until we find buyers for them.
I'm also going to add the option of having the pill lip removed for free, which makes it easier to heat sink your drivers. This is obviously done automatically for those who order the "hot option" kit.
