Trading Desk

Hi guys. Im getting into forex trading and want to set up a decent trading desk. Maybe someone has some experience or ideas?
Im thinking of getting a router with 2 WAN Ports and a UMTS Card slot. I would have ADSL and ISDN, and if all that where to fall out it would auto switch to UMTS.

Now PC HW. We want 2 computers running/mirroring constantly. If one dies the we should be able to continue working on the other straight away.
Im not sure how I should do this, I WAS thinking of setting up a small server rack with 2 or 3 old servers in it, and Ubuntu, XEN and Ganeti, then just run 2 VMWares running and access them with some sort of a thin client…

Would appreciate any ideas on all of this!!

Thanks a mil guys!
