Crypto currency mining

Have not done anything further about soundproofing as at the colder weather temps, fan speeds and noise is lower anyway.

So I have been looking at moving from CryptoNight to Eth on my AMD rigs. But it's a bit challenging with the BIOS mods, clock and miner settings and while the GPU's were just fine in close proximity on Onda motherboards for CryptoNight they are getting too hot on Eth.

I am also going to make a micro rig for my 1080 Ti's that are currently running in my old computer as I need something to keep one of my small bedrooms warmer. I bought this motherboard with integrated CPU for £25,
it's only 17x17cm https://www.ebay.co.uk/itm/Pegatron-...53.m2749.l2649

I will put 2 Ti cards on it with adapters, 1 either side of motherboard, one upside down so that both have fans on the outside and blowing exhaust in the same direction. The PSU will go on top of motherboard sucking air from the motherboard and blowing out in the same direction as GPU's. On the top will go acrylic or similar oversized panel with a a picture or artwork. This can then be attached to the wall high enough for kids not to reach it , blowing warm air downwards and looking like a piece of art.

for micro-rigs with a secondary purpose

Can you split that single PCIe port?

I could and I have 1 to 3 splitter. It was not working well on Microserver, I thought it was splitters fault and have not used it since but it was a bit dodgy on Microserver even with one card without splitter so the splitter might be OK. There are other versions like 1 to 2 and 1 to 4 as well, possibly even more. My friend is using 1 to 2 without any issues. The bus bandwidth is not an issue, each card only uses 1-2% of available bandwidth running on Gen2 x1 PCIe slot.

On this one the idea is to use 1x normal riser and 1x mPCIe riser as that should be less bulky than using splitter.

Also I think I will skip the mSata SSD on this one and run EthOs from USB stick if I can get WiFi working on it as I do not want to run Ethernet cable to it because I have not any Ethernet sockets in the room I want to use it in.

Well, I have 2 x L3+ Antminers (inc. PSUs) just arrived this morning.

Still not sure whether to keep them or sell them yet. They're selling on Ebay for as much as £3,500 (inc PSU). Not counting any loss of cryptocurrency investment profits (since I used crypo to purchase them), I think they cost me the equivalent of about £1,800 each, including PSU, shipping and duty.

If I decide to put one/both of them on Ebay, I'll probably put them on at a £3K reserve. I'd prefer payment in BTC, so if anyone here is interested in one, I'm happy to sell one for somewhere in the region of 0.25 BTC (inc postage), which would give me small profit. Probably not as much profit as I would've made had I kept the funds invested, but just about enough to make buying them worthwhile I think.
