But I am a SUPER geek and I have build so many custom things just to get in the top 10 on futuremark or in the old days to get to first place! (Futuremark benchmarking the faster user computers in the world)1.) Which operating system to install?2.) Which motherboard?3.) Which CPU?4.) Which memory?5.) Which power supply?6.) Which hard drive?7.) Which video cards and how many?8.) What to mine?9.) How to build the system with racks to hold the video cards, motherboard, hard drive, power supply...I will go over these one at a time.1.) Which OS:Well there are limits and it depends on which CPU, how many video cards are you going to use. Linux has no limit on video cards you can use use as many as you like! But make sure Linux drivers work for the cards! I haven't had a problem with any Nvidia cards 750 to 1080's all work. But AMD/ATI cards no so much. :( Windows 7 you... less
