What about a server like a HP ML350 G6? Fits all your requirements including ps2 and serial ports. Only downside could be cost of memory. They run quite quietly for servers.
Just a thought. Andy Sent from my Android On 5 Jan 2013 04:07, "Russell Coker" <[email protected]> wrote: > On Sat, 5 Jan 2013, Andrew Voumard <[email protected]> wrote: > > > > 6.
