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.
no problem hope it works out for you mate
