Hello guys, I have always used pre-built PC's like Dell Asus ect. I have now decided to build my own Desktop Pc. My PC will not be used for gaming. It will be used as my stock/options/commodities trading PC. It will be on 24 hours a day. It will be running about 4 automated programs (doing multiple calculations). I will have 4 monitors connected to it (24"-27"). It has to be reliable. Need to have a fast hard drive. Needs to stay cool. I am not sure if i need intel or amd processors? i need a reliable hard drive and quality components. My budget is approx $1000. (I already have the monitors - they are all HDMI's). I can do i5 but i would like to go with i7. I was told by a good friend of mine to use dual xeon processor older HP or Dell T5400 and upgrade it as they are super reliable. Any input will be greatly appreciated ! Thanks guys !
