Hi
"mikemc" - If you talk about CNC then I don't know which hardware it has got. My friend made it but he didn't tell me what he built in. If you think on hardwere in computer it is not special. The computer
has 3 years, with processor Pentium Dual Core 2.5GHz, HDD 300GB, RAM 4 GB, graphics card is built on base plate. For drawing you need at least Windows 7 64-bit.
If I would keep direction of Solidworks programme then I will need graphics card GeForce with 2Gb memory at least, processor i7 and RAM 8GB.
CNC is not only for RC models but it has used for many things. My CNC is enough strong for aluminium. Everything is dependented on how much money you will prepare to pay for CNC.
