Performa Internal HD

[Mervyn & Giuliana Bond]

I have a faithful old PowerPC Performa 6400 with a 1.6G hard drive. 
The HD is somewhat crowded and burning a full CD is now impossible.

1.	Is it possible to replace the internal HD with a drive of 
greater capacity?

2.      If the answer to 1. is yes, is this a favoured option?

3.      What would be the likely costs: parts and installation?

Comments please.
