So I'm giving a bit of leeway here because as stated this is a garage assembled miner. The photos will do you no favours as hagss pointed out while I'm typing.
Honestly, it doesn't look like so honest.
It's just an empty pc case.
**POSSIBLY A SCAM ATTEMPT UNTIL PROVEN OTHERWISE**
I know you said in there you are still waiting for the hashboards to assemble the miner, but I'd expect you to have photos, or at least a page with photos and a description of the boards/process getting them made.
Edit: Also a description of the chips being used and how many would also go along way in the miner description.
You and your partner should post your photos on the site, you are after all looking for investomers.
Now assuming the hardware is real, can you give details on the PSU as it states 2000W, for a machine stating 1850W usage with a 10% variance
