I have been using my Synology Disk Station DS109j for almost a year now. This is an amazing piece of hardware that occupies almost no space on my desk, consumes almost no energy with its auto-sleep settings and works as an all-in-one print/web/ftp/media/sound/iTunes/photo/file/download server. Last weekend I have installed there an instance of Subversion, making this small box a source code manager for our team.
If you already have or are planning to buy a Synology DS and want to have your own Subversion to manage your source code, the installation is very simple and is covered in details in Step-by-step guide to installing Subversion provided by Synology guys.
Any questions are welcome.
