I'd like to create a mini dropbox and print server on a small soho network of 5 users (all of them use windows XP desktops). The device need to run 24/7 or at least 12/7 (I can accept just workday hours too but the other two options would be better).

• Dropbox mini server: I mean I will have a 90gb dropbox on every computer on my network LAN syncing with It and the one onto It syncing to the web.
• Print Server: I have Samsung SCX 4521F (fax/print/scan/copy), Samsung ML2010, HP Laser jet P1006, HP Color Laserjet CP1215, HP Office jet pro K8600, HP Design jet 500. All of them now are connected using little print servers and I want to get rid of them hooking everything to this mini server. The fax/print/scan/copy machine need to stay connected to a PC to make me able to use the software that comes with It. The mini server would save me on this too.
• Fax/Scan server: since I have the above mentioned fax/print/scan/copy machine I would like to make people use It from/to their computers through the mini server.

I thought to a recent EEEBOX machine because I heard good things about ATOM cpus and because It seems that a recent BIOS version could switch It off and on autonomously.

I'd like to listen some advice from You. Best of all would be:

• If You have something similar running for a long time
• If You disagree with this hardware choice and If You would suggest some other device.
• If You see any issues with my printing setup
• Anything else ;)

My budget is from Zero (using right sw to build something on top on a old PC) to 500€ max.
