Wisdom of a move to Linux?

Hi All, At risk of being flamed as an RTFM or SIOYA, and confessing to not knowing a great deal about Linux coming from an RS/6000 AIX background, I got back from leave today to find an unexpected corporate re-think. I am told that a task that was being aimed at a: 4 processor RS/6000, AIX, Informix IDS 7.31 client-server, 1 Gb memory, 75 Gb (with probable expansion to 5 times that) database, 30 users is now being aimed at a: Dell PowerEdge pentium 3, Informix IDS, Linux Red Hat... Immediate questions in my head (other than 'please can I go back on leave'): 1) Is this remotely viable on a PC under Linux? 2) How big can Linux handle? I know akin to 'how long is a piece of string?' But is an application of 30 users into a 300 Gb database relatively small, medium or approaching limits for a PC based Linux system? 3) Any ideas of real application sizes of Informix on Linux successfully in the real world? 4) Any particularly nasty holes/experiences I need to watch out for? Any feedback appreciated.
