I like your site....yours is the reason why I posted this. I am thinking of getting a Synology NAS and doing the same!
I like using my Synology NAS because it makes moving files around easy and fast within my home network across several PCs to the NAS. It's a large upfront cost and will take several years for a payback on the investment but I also use the NAS for backing up PC's, storing and streaming video and audio files, etc. I had used a service for years but ftp issues led me to use my NAS, which I had already purchased as a backup device. Once I realized I could host my site, I purchased a new, faster NAS that is now going on 3 years old. If you go this route, just be sure to follow all the security protocols that Synology provides.
