Ok, let me see how i can explain this, I'm living in the us right now but still have some properties in my country. So with that in mind getting the USD out is not a problem.
1.- "0.7-1w/gh stuff" I was thinking something more along the lines of Antminer S5s maybe 2 units and a thermaltake psu that can take a beating.
2.- The Rig. I'm not used to having a mess all over one of the rooms, so I Was thinking of starting with a rack, but not sure if the S5s are rackable.
3.- The internet connection. We don't have super fast internet speeds but its pretty stable. So taking this in consideration, I don't think the rig needs a designated router thats out of the ordinary (linksys, dlink, etc.). What do you think?
4.-Although its hot outside, inside there is a very powerfuul A/C unit that for a small space it has 5 tons of A/C. So that doesnt worry me much.
5.- Define ESCROW.
6.- And finally thank you for offering your help and will keep in mind if I get stuck on another topic. This conversation has been very helpful and much appreciated.
S5s are not rack-mountable. Only even numbered models in the S-series can be racked (ie S2, S4, and future S6).
You will pay a lot extra per TH for S5s, because of their very low efficiency (I think they are actually the best on the market), so I don't recommend them. If you're looking for good, compact hardware, I would suggest S4s. Zoomhash has some in stock, I'm not sure if they're legit but you should be fine if you do your research beforehand. Also, Spondoolies SP-10s, I've heard, are 100% awesome. Easy to set up, run very stable, good power efficiency (0.8w/gh), and rack-mountable. If you can find those, consider yourself lucky!
Your miners do not need a special router at all. The difficulty of setting up most miners is about the same as setting up a router. You'll need to connect to its local ip (most connect directly to your network via an ethernet cable, they have integrated controllers). Once you get that, all you have to do is input pool settings and it should start mining. As long as you are computer literate, you should be fine!
These miners produce A LOT of heat. A 1300w miner (S4) will put out 1300w of heat, about a standard baseboard heater. Your A/C unit will probably be overwhelmed once you have 2 S4s running, unless it is really powerful. Don't go all in right away, try at most 2.5KW to start, then work your way up if you can support more.
Another note, these miners also produce a lot of noise. Expect them to be as loud as a hair dryer, so I hope nobody sleeps in the room next over.
Escrow is when you send your money to a trusted third party who oversees your transaction. Lets say you buy a miner from Bob. You can't trust him to ship the miner after you pay him (he could take the money and never ship), and he cant trust you to pay him after he ships the miner (you could not pay him and take the miner).
BUT, if you both trust Alice, you can send the money to Alice first. Then bob will ship the miner. Once you confirm you get it, Alice will release the money to Bob. If one of you scams the other, Alice will decide who to send the money too. This is how escrow works.
