If it is only one newsgroup, the whole 60 days doesn't take up much space.
But make sure you compact your folders often.

Click on Outlook Express at the top of the folder tree so no folders are
open. Then: File | Work Offline (or double click Working Online in the
Status Bar). File | Folder | Compact all folders. Don't touch anything until
the compacting is completed.

How often should I flush all the data cache (posts and headers) for
newsgroups for the OE newsreader?
1GB dual channel RAM, free reign swapfile, GBs of freespace. News group
downloads is set at 1000 max per group. Only the headers are auto
downloaded.
