Indeed I am, component pricing here is pretty crazy TBH. Interesting re PCIe slots, I'll have to look into that for sure, I might be able to get more than the 3 that I had thought possible.... I'd say the power supply would feed all of them. I currently have an radeon R9 M360 card in my cpu /gpu rig (which is also my desktop). I'm getting about 62 Mhz on DEC and 10.44 Mhz on Eth on GPU (overclocked to 1050 Mhz GPU with 1350 Mhz memory overclock) plus an extra 230 h/s off the cpu XMR. Not a lot, but between all my CPU miners I am getting 1.3 -5 Khz for XMR.
I'd like to get a much better Mhz on this new rig and I'm going to be free to play with Bios Etc on this one as I dont have to work on it!

Might want to double check the power supply here though, I guess it depends on the GPU, my understanding is that the AMD cards draw more power depending on what you're mining and/or if you're dual mining with them. nVidia cards generally tend to draw less power, but, by how much, I'm not sure. I currently only have 2 AMD RX 580's plugged in mining Electroneum, and the total system draw at the plug is 374W. If I recall correctly, system draw without the GPU's in was aroun 85W so that means the 2 cards mining are pulling roughly 290W between them.
Most posts I've read here recommend that the PSU should be maxed between 40 - 70% of their rated power, so I'm guessing you'll need to factor that in, so as not to blow up your PSU
I have been playing with HiveOS as the OS, its really nifty once you get your head around the wallet configuration. Give that a shot too and see how you get on. It has tweaking options from the web interface too, which, I'm guessing get applied automagically. I've not tweaked the AMD cards, as the bios's have been modified, so, I'm banking on them being tweaked already.
