>If your customer's buy their own HW (and are VERY stingy), get them up to a level which is nowadays also obsolete and can be bought very cheaply: something in the area of at least an old celeron(900Mhz), PIII(800Mhz), Duron(800Mhz) or Athlon(750Mhz) but with nowaday's cheap memory and hide, until all these systems are up and running <g>.

For $200 you can get a brand new Athlon 1gz, 128mb, 30gigHD machine from TigerDirect or Wall-Mart online. They come with lindows but you can install windows on them.
