RX 470s are very popular because of low power usage, and cheap card prices.  RX 480s can be just as good, provided you find one on sale.

What to buy for 1 mining unit
best speed/price/power usage per unit ?

cpu: athlon II x2 20w - $15 used
mb: ga990fx-ud3p/msi 890fx gd70/any board with 6 pci-e - $60 used
ram: random non ecc ddr3 4gb - $10 used
psu: cheapest 1kw+ gold psu from reputable brand (corsair, xfx, seasonic, evga, delta, some rosewill, some thermaltake, among others) - $100 new
gpu: rx470 4g with elpida or samsung ram - $160 new, x6 (undervolt/underclock core and mem controller, overclock mem modules, and strap mod the bios)
risers: x1 to x16 non powered if your card has 8 pin & doesnt use pci-e power, else x1 to x16 usb cable powered riser boards ($2-7ea, new)
heatsink: alpine 64 gt - $8 new
hdd: random cheapest working sata drive - $7 used

*if power is a serious issue, use 80+ plat psu and ssd, maybe nvidia cards but they are much more $/mh
*if building many rigs then get all new parts for less hassle, like h81 pro btc v2 with pentium cpu
*rx470 4g cards that can use unpowered risers that i have tested: msi gaming, msi armor, gigabyte
*estimated speed: 28mh/s eth + 420mh/s decred per card
*sometimes hynix 470s or 480s go on sale for much cheaper, get those in that case. hynix 470 does 26.5-28mh/s depending on how tolerant it is to OCing

Rx 470s/ Rx 480s are the current best at mining eth, you can also go gtx 1060 if you're mining Zec but i would go for amd, if you can find an asrock btcpro h81 along with an old cpu/hdd/4gb ram module, you'll just have the power supply to worry about, a good one shouldn't cost more than 120$. you can also check out Pandaminer.

Do keep in mind that ETH is *supposed* to shift to Proof of Stake sometime this year - at which point all the ETH mining will be looking for new homes, driving the difficulty of all other coins in the "basket of appx equal profitability" up a lot very very quickly.

You can boot off of a usb for an even more ghetto setup- that'll save you maybe a few bucks off of the overall build. Unless you're running Windows for some reason that'll do just fine for a mining build.

Right now I'm buying high throughput hash power in reduce time windows with nicehash to do solo mining.

The problem is that you could loose all the money, but if you know how to calculate the odds...
