Typically a single core x86 1500 MHz CPU with 512 Mb of RAM will run faster than any Windows Multi-core machine with many gigs of memory, so that's what I want to have built. The graphics rendering of the GUI will possibly slow any machine down. So a 32 Mb card is to be used I do want the RAM to be expandable to 2064 Mb though only recent converts from Windows will ever install it.
