Glad to see this new board, I'm also new to this forum.
I would like to share a good platform here.
QNAP Turbo Station series. (TS-109, TS-209 series, for 1-bay SATA HDD and 2-bay models).
1. It is easy to install lots of PHP-based applications, e.g. phpBB, wordpress, etc.
2. with NFS support, it is easy to have a storage expansion or additional backup volume by mounted the NAS to your application server.
Some of my firends got good experience to install the Yellow Dog Linux on PS3 hardware, and run certain applications for his small business. And use these NFS supported NASes as storage volume.
Do you think this is good application?
