I am searching for an older pc to use with my cnc machine and am looking to stay within the 230 range hopefully. I think I may have found one Dell GX620 SFF WITH Mon--2.8 DUAL CORE /160 HD/2 GB - eBay (item 190517071919 end time Apr-26-11 20:53:30 PDT), but see good /bad reviews to both extremes with this model and am open to suggestions. I am looking to have my autocad, artcam, and mach3 programs all onto this pc so I don't have to use an external hdd to move files from autocad/cam between pcs (which may be necessary in order to just have mach3 on it). Any advice or recommendations would be appreciated. Thank You
