I do something like that. My ISP offers only POP3 mail delivery, and I use 
KMail as user agent, which was weak in that area the last time I tried it but 
it's fine with IMAP4 (I was told that none of its devs have a POP3 account to 
test it). My solution has been to run a local mail server, with fetchmail, 
postfix and dovecot. Fetchmail collects everything from the ISP every five 
minutes and forwards it to postfix, where dovecot serves it to my PC as IMAP. 

All this is done on a small local server, but it could equally be done here on 
the desktop machine.

The only difficulty is in setting postfix up to act as final destination; I've 
asked for help with that here before, and I'm not sure I have it just-so yet. 
It may still be insisting on forwarding some mail elsewhere; I haven't checked 
recently.
