About to build a small footprint PC with a Dual core Atom Processor, this is purely to run mach, space is a premium so ITX offers the size BUT it has only 1 expansion slot (pci) and one parallel port. it has on board Graphics and this is my worry. do people tend to have problems with on board G.cards. I could fit a pci G card BUT if I run 4th axis would I need another parallel port and run into a dead end.
