I want to build a dedicated astronomy computer with USB 3 as well as at least 8 Meg's of ram. I would want a small footprint case for use at the scope. A CD/DVD slot. Also would like PC slot for expansion. Would prefer Windows 7. It's got to have lots of power for about 8 USB ports. Quad processors. Only need 2 USB 3 ports. Wifi connection necessary and FireWire and Blue tooth would be nice. Large, fast digital hard drive. Anyone who can build one for me or point me to a website that builds custom computers? You can reply to my e-mail at vikelj(at)comcast.net.
