My little jack-of-all-trades home sever:
Motherboard: Asus M4A88TDMUSB3
CPU: Athlon II x4 640
Memory: 4GB (4x1GB) DDR3 1333 ECC (my boss gave me these for $10 a piece
PSU: 600w....forget the make. Had this laying around and it still kicks.
OS HDD: 320GB 7200.10 Seagate. Had this laying around from an old build. Runs like a champ after 5+ years, no bad sectors at all.
Storage HDD: 2x1 TB 7200.12 Seagates. Thinking of changing to a RAID 5 in the near future.
What you use it for:
File Server / Media Streaming
Newsreader - SabNZB+ downloads, repairs, unpacks, and sorts my downloads. And discards the archives afterwards.
Home Surveillance 'Server' - cameras connect to the server and dump their captures there.
Once I get out of my apartment I'll also be using this as an Untangle Router.
Thing is almost dead silent and sits right next to my TV. Only thing you can hear from time to time is the aging 7200.10 drive whenever it gets starts getting pegged for a while.
Pics to come.
