Many thanks guys - I think by the time Dell got to this design of machine, they had moved away from their dedicated components philosophy - it is a standard board for the period in this machine, with standard RAM and PSU. And again there's no BIOS/OS interlink here and the HD is SATA.
However the points that you are making are all very valid and I thank you all for going through the 'Disadvantages'.
So
Low Cost Possibly retain all applications Retain XP (for the moment)
MB form factor RAM incompatability PSU ditto (chickened out of typing that twice!) Hassle factor getting it all to work
and so on for the other ones I can't remember, but that's enough to convince me, though I will lose the fun of doing an Ebay search, bid, etc., and I'll need to set aside some more pennies.
Again many thanks
Rob
