Looking for a PC that will run ArcGIS at a proficient level for my university coursework. I've managed to get a copy of the software for free from my university. I don't want to build the PC myself but I do want to buy from Overclockers as a sort of system configurator build. I'd like the system to be easily upgradeable in the future in terms of adding an additional SSD, RAM and perhaps a better graphics card if needs be. I need a mouse and keyboard as well as an OS. I already have a widescreen monitor sourced. Budget wise I'd like to keep it around the £600 mark.
