I don't know how anyone does it with any less, in fact I need more to see with.
(8) Dell 2010's (2) Colorgraphic Quad PCI/PCI Express cards. One Dell Precison 640 (2) 3.6 Xeons and 4 MB RAM. (2) Internal RAID Hard Drives, (1) External Networked Maxtor for backup redundency, and another maxtor directly into the workstation. Dual WAN via a Sonicwall TZ170 with flow modulation, Cable 8MB downlaod, DSL 6MB download. If one goes out the other kicks in. Both bandwith is used and modulated for normal use.
I spread trading software, charts and news software all over them.
