Which is a good reason to get one now. I have one (running FreeBSD and ZFS), and it has been great. I does what I ask of a homeserver: it runs silently and is pretty good at saturating a 1Gb connection, the RAM really helps the performance. All at a great price.
Do you have one of these? Can you answer some questions for me, as I'm just about ready to impulse buy!
Is it passively cooled? Is the "embedded raid" an actual RAID or some junk software emulation (I'll probably use ZFS anyway, and that should be used w/out hardware RAID)?

Has ECC RAM support. Takes 4 3.5" hard disks, and runs very quiet and cool.
