I am also interested in this
I want to have a NAS wired Or wireless with Bit torrent download support
Low cost (under 5k) Low Power Usage (under 50w) Compact

What i have.
1) I have two Wireless Router (which consist 4 ports each)
2) I have 640 Seagate SATA II hard disk (recent purchase around 2 week)
3) Sata to IDE convertor
4) 350 watts SMPS (repaired)
5) will purchase cabby from scrap. or will make one by hand...

I have some option for NAS
Apical TS 350S-LS which cost around 4.5k
Support SATA I, II to USB2.0 and RJ45 connectivity.
Support BT Download/Upload stand-along operation while PC is off (BT NAS version)
Support HDD format FAT 32, XFS (That means it doesn't support NTFS too bad how can this be a NAS)

If you see closely Maximum of this enclosure will surely have one of this problem
1) NTFS support
2) Larger Hard drive or Upgradability support Above 1 TB or 2 TB
3) 10/100 Mbps only
4) No wifi
5) Less info about the bit torrent version, compatibility, stability, etc
6) IDE or Sata
7) USB port 1.1 or Missing

I don't care about heat or Noise I care about work...

there are advantages of this enclosure.
1) Compact
2) Low Power
3) Quick Boot Share or i can say Active boot and share.
4) Torrent download (obiviously if it works atleast 2 active and some scheduled)


So can any one suggest a Good alternative ?

1) Download stuff from the internet via Bit torrent, ftp etc
2) Sata connectable.
