Very attractive indeed, sir. You might even be able to allow .htaccess, 
because Apache won't take down the rest of the server(s)!

If I just did my math right, that's 107~GB? I'm surprised it's not more. 
I would say then that in interests of growth, the NAS(es?) we 
hypothetically purchase contain at least 1.5-2Tb in them each. That 
leaves plenty of room for storage of bother user and system data 
(assuming we were storing the VMs there as well, which would be a 
GoodIdeaIfYouAskMe).
