I dont think anyone has since you can still sell S1 for $110 on ebay.
S1 may or may not go up big time at first till we do .
Id rather pay 150 US in the US for one then buy it off ebay, in some cases eBay is great but as some one said about eBay the cheap ones on eBay are most likely on there last legs and well used and sense no one really knows for sure that Ive seen how the upgrade works i mean what condition the old S1 need to be in what does it replace . etc etc . expect what the add said you get two boards and some other stuff which looks like a normal upgrade kit do we need the old boards etc etc
I might be wrong can't say i only buy certain things off eBay then it's new.
.
i see why he would require the two kit buy some will buy the kits just to build two S3 at a very reduced price if all you need is the heat sinks and frame .
over the years I've found when doing most upgrades you don't need the old one , its just makes it easier if you have it .
well any way I'm done just my 2s worth sense i have not seen just what it does . my bad you get with the kit
1. 2 units of hash boards
2. 2 units of mini customized heat sink
3. 1 unit of adapter board
4. 1 unit of control board holder
5. 1 fan including the fan's cover and screws
6. 4 units of white plastic brackets, 2 units of 2x10 pin cables, 8 screws, 8 spring screws, 1 bag of thermal paste
buy looking at that you won't need the S1 in any way just a the kit and a little no know how unless the S1 has some thing on it you may need.
hm can't wait two S3 for the price of one all you do is put it to gather which some can't do
