*** What Do You Think of This Rig? ***

[itos]

I have been mining with a R9 270 but now I want to build my own rig. I want to at least have a 2000kh/s rig. Here are the specs.

The Rig

Motherboard: MSI Computer Corp. DDR3 1600 Intel LGA 1155 $151.27
CPU: Intel Celeron G1620 2.70GHz LGA-1155 Processor $42.99
Ram: Kingston Hyper X Blu 4 GB 1600MHz DDR3 $43.74
Graphic Cards: Gigabyte R9 270 $209.99 x 5 = $1049.95
PSU: Rosewill CAPSTONE Series 750W 80 Plus Gold Certified $99.99 x 2 = $199.98
Cable Connect PSU: Add2PSU Multiple Power Supply Adapter $29.95
Cables: PCIe 1x to 16x Powered Flexible Riser Extender Cable $14.79 x5 = $73.95

Total Investment: $1591.83

Some questions:

What cooling system do you recommend? A fan next to the rig? My city temperatures are high.

Do you recommend me to spend a little more for the Platinum certified PSU instead of the Gold certified?

What do you think overall?
