why not try litecoin cloud mining?

Litecoin Cloud Mining

Because I've concluded the price of a KH/s is destined to exponentially decrease over time. A price of a GPU card is too, but the drop is not exponential.

I've concluded this based exclusively on Bitcoin cloud mining (see https://cex.io/), the situation might be different with litecoins and other scrypt currencies. I will check out the link you sent me, it looks very interesting. Thanks!

You need 1X riser 3 PCS and 16X riser 2 PCS so you can add you 5 GPUs.
By the way what PSU are you using? Be sure for that also

I still don't know what PSU to buy, since I don't know which GPU models I'll use and how to correctly compute the required voltage. Thanks for pointing out this problem!

Use powered risers. Also get this motherboard it's cheaper: http://www.microcenter.com/product/382952/970_Extreme4_Socket_AM3_970_ATX_AMD_Motherboard

Seems better indeed, thanks! I hope my reseller have this. I cannot import expensive goods from the US without paying, so I need to buy gears inside of the EU. PCI risers cost 9$ on amazon but if you live in the EU prices starts from 12 ( = 16$) which is insane. Not to mention the powered ones, which I saw for prices starting at 25.
