I've been looking at some options for a small home server. I'd like a 24/7 system for these functions:

VOIP (MagicJack, Skype, etc)
Media - visual
Media - audio
RAID storage (external twin hard drive appliance)
FTP (accessible by net)
VNC (still learning, what is this?)

The system would have these qualities:

Quiet
Small
Low energy consumption
Robust
Durable
Future-proof (ready for new undefined tasks)

I've been looking at thin clients (it's your fault PT) and small form factor PC's which include:

thin clients:
HP Neoware e90
HP KF351 AJ
HP Neoware e140
HP KF424 AT

PC's (inc barebones):
MSI Wind PC
Shuttle K45 Box
Asus Eee Box

For the moment, the MSI Wind is my favorite. Add a gig of RAM and a solid state internal hard drive and it should meet these needs simply.

I'm starting this thread asking feedback on my choice and hopefully provoking a larger discussion.

THX, have fun!
