Recommended PC for CNC

[catabolic]

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

Don't forget to look around on craigslist.org too, lots of deals there if you get on at the right time.
