Sounds like a name-brand Dell, HP, etc. Overpriced to buy and overpriced

The solution to the flash problem is to use the 32-bit firefox and
associated components for multimedia. Then the flash player works just
fine. You will need to get the 32-bit version of xine, mplayerplug-in
and the associated requirements all in 32-bit. Happily, the 32-bit stuff
plays very nicely in a 64-bit sandbox!
You will need to tinker and make pulseaudio run on the server so that
flash will be happy.

Load up K12LTSP-EL v. 5.1 (Centos based) and use the 64-bit version so
you can use directly the full 16GB RAM. Don't bother with the vmware
slices as it won't get you anything of benefit.
