the time has come when its painfully obvious that >1w/GH gear will never be useful again, and Ive got a bunch of S1 units and BE200-based boards lying around taking up space.

ive already stripped off aluminum frames and heatsinks for the scrap metal, and put the fans in thier own pile, but what about the PCBs?

Is there any real resale value for the individual parts such as inductors and regulators (mostly TPS53355 or similar)? Is it wort my time to serepate anyting in particular (or at all) before trying to get base scrap value on the copper PCBs?

I think as "collectors items" may still be the best price, and/or have considered desoldering BE200 chips for individual sale

I got a bunch of old KNC Jupiters and wondering the same thing.

However I doubt I will get much for the aluminum and copper heatsinks or the PCB boards. I think if you go to a scrap yard and donate a 2 ton car they give you $100 but a few grams won't be worth much.

most places give $200+ and will even tow your car, and they make $200-300 on scrap metal, plus any parts they think will scrap for resale. but thats mpainted metal, mised with oil, dirt, rust, glass, fabric, etc.

im seeing scrap value of aluminum to range $0.40-0.50 at most recyclers depending on quality, and anything from $1-$2 for a pound of PCB (mainly for copper content). for an S1 you might be looking at $5 scrap value. I think the PCBs could be potentially sold for collectors though on their own for $5 each, or to someone who is interested in specific regulators that cost $3-5 otherwise and tere are a few per hash board.

I had good luck on Craigslist or Kijiji getting rid of my unprofitable miners, maybe try that.

Also parting it out possibly for those still using them that want replacements.   You might be able to find them on the board here or ebay.   But I would try this before completely scrapping it.

I have only had to part one miner out was a C1 and I did decent considering, but it did have a lot of parts.   Old miners like the dragon's and A1's I'm sure there are some who would buy boards at decent price.   

And if you are lucky craigslist as no shipping so really better on heavy old miners like A1's.  But if your like me in middle of no where CL is not so good for this.

stuff using >1w/GH is truly obsolete, even with free power it just makes way more sense to get 0.5-0.7w/GH gear for dirtcheap already/

Im sitting here staring at the pile of S1 boards (heatsinks removed, thermal paste cleaned away), maybe i can get $10/ea on ebay as collectors items. Not sure about the SP10 - its rediculously heavy and easily replaced by a $100 antminer S5.

If you had some A1 Dragon, I'd take a board. I've got one at the shop with a roasted board and I'd just as soon it was complete for the museum shelf. I'd consider some H/M board Bitfury stuff as well; right now I have one backplane with 8 working slots and 10 cards to put in it so some more cards and a working backplane would come in handy.
Not so much on the S1 boards; I have 15 S1 at the shop in various stages between "in the original packaging" and "replaced parts for undervolting". Maybe if I can get a pod project going, and I burn through the hundred-odd TPS53355-laden boards I already have (which would be pretty sweet, I'll be honest) I'd want to take in more but unless I get ahead enough financially (and chronologically) to run the dev, and get some actual cooperation from a chip manufacturer (instead of silence), that's definitely a stretch goal.

Have you got a rockminer rbox (110ghs version)? If it's working I can pay for shipping to the UK :)

no, but i do have at least 1 (maybe two) of the 32GB r-box, which was way more adorable in my opinion. its like a pokemon that hasnt evolved into its final form yet <3
Includes all original packaging (it was tinkered with a bit, but i mostly bought it for my own collectible pile. Im open to offers, though shippng to the UK is pricy and slow

Ive considered renting a hot air gun and vacuum tweezers to remove regulators and ASIC chips myself, is there any market for that (like you, id probably pull 100+ TPS53355 or similar bucks)? im not very experienced at it though, so its likely they'd need a secondary cleanup to remove any remaining solder

The Bitfury M-board and at least 4 H-boards I plan to keep as they are pretty uncommon at this point (and *fingers crossed* might be compatible with the next bitfury consumer-level gear), but that still leaves 4-5 H-boards im willing to sell.

my goal is to offload the biggest stuff first. that means the aluminum frames/heatsinks for the BTCgarden/AntminerS1 units, and figuring out WTF an SP10 is still worth (considering an S3 with similar specs and 1/4 the weight costs <$40). Its gotta have $15 of scrap aluminum in it at least

EDIT: added some power breakers (QBH style) and a fancy L21-20 outlet to my list

I have got 500+ Neptune cubes I am going to have to scrap in a few months.  I wonder if I can sell the heatsinks and fans for more than the whole units.

If the neptunes were anything like the jupiter, the CPU mounting bracket wasn't included so you couldn't sell them for a CPU.

Why not give it a try on the computer harware section?

I know some people who would probably buy hem for the right price, neptunes are silent and powerful!

Hell I'd give it a go for the next winter depending on where you're located for shipping (I'm in EU)

If you can find out the cost of shipping and let me know how much you'd like for one I might be interested subject to cost)  :)

I've got some of the 100GH New R-Box dead from CrazyGuy, could probably fix one up and get it your way when I have time.

I do not have any of the pod R-Box though, interested in that.

I also don't have any Neptunes. I actually don't have any KFC gear in the museum.

Unfortunately, I also don't have any budget for the museum at present. But hopefully I will by the end of the month.

How much would you want for it (including shipping to the UK)? I'm after the 100gh ones only a couple to have a little micro mine set up. Electric cost killed my two s3+'s so they've gone now. Although I've still got a half dead one. Only one board works.

Why don't you visit a mining rig store to ask if they have some sort of electronics recycle program?

Check your mail in the coming weeks, I'll have something for the museum at your door.
