I guess its either Qnap or Synology
I have a Synology 209+, im rather pleased with it, and all the options Synology are providing
I can download from it with 60mb/sec and upload with 50mb/sec
Im currently using the squeecebox server and im about to use the mailserver, webserver, mysqlserver and phpaddon aswell
for the discs i chose seagate or samsung myself (because of the price) but now that its gonna run 24/7 im hitting myself for not buying the WD Green something, discs, which got a lower powerusage
