I would offer $9300 for the lot if your interested. I live in Olathe, so we can pick up the units, but would you potentially be available to help set them up if we make a deal, we could include an extra charge for the assistance with smOS and cabling set up? I have not worked with multiple PSU's per rig before, so I want to make sure there won't be any issues and we can get setup and running with no problems.
As the helpful poster just above me noted, running dual power supplies, much to my surprise, turned out to be a non-issue. I read plenty of people recounting how it was nothing but trouble, and I originally intended it to only be a stop-gap solution. Whether it is due to the PSUs having good voltage control or just because I am lucking, I have not had a single issue with running dual PSUs. In fact, it has turned out to be nice from the perspective of savings in not needing to buy the extra large, extra expensive PSUs.
As for your offer, I have to admit that I saw you posting in another for sale thread where you mentioned you were located in Olathe, and I was hoping you would notice my listing. Avoiding the need to package everything up and ship it sounds awfully enticing, but $9,300 is a little below where I want to be. Given the benefits your offer entails (i.e., your location) I'm willing to go a little further than meeting you halfway. How about $9,700, and I will be happy to assist with setup.
If you need any help justifying the price to yourself, I think I mentioned in listing the that it includes extra risers. I haven't counted recently how many extra risers I have, but I believe I have 5 or more risers that I will throw in with the deal.
Let me confer with my partner and I will get back to you. We would have to figure out something on our end as our partnership has about 9500 in btc and cash currently, and we want to keep a little just in case we need something. Would you consider 9200 and a note for the remaining 500 to be paid over 3 months at 8% interest? Obviously we would meet up, possibly have a beer and chat, and make sure you have everything needed to trust us, but I am just spitballing some alternative ideas. Please let me know your thoughts.
