For best HDD performance , you need to look at keeping as close to 25% free
as you can. You should also make provision for the installation of other
applications, service packs, updates, space for shadow copies, restore
points etc.
Anything smaller than 40gb will leave you trying to free up space
continually in a bid to keep performance at a reasonable level. A 60gb
partition will give more freedom and reduce time spent deleting stuff. An
80gb partition will ensure that you don't have to worry about space for a
while.
Ensuring that the OS partition is large enough now will save buying Acronis
TrueImage or similar and running the gauntlet of cloning the OS to a larger
drive at some point in the not so distant future..
