New PC configuration

Since we need to buy a new PC (ours just reached its limits !), I decided, it would be more fun if we build it from scratch instead of buying it all set up.
It also gave me the opportunity to figure out what was out in the market and learn more about the state of art of technology.
First, to define what are our needs, I need to say, the PC will barely be used for playing although it might sometimes... I want it to be a tool for working : installing several OS's (Linux, XP, Solaris), sharing files with the laptop over the OS's, building a Wifi network at home, surfing the internet, mailing, writing letters, designing with Photoshop, building movies from home-made videos, and so on... and as silent as possible !
Here's what I ended up with :

Peripherals :
- Flat screen : Viewsonic VX912 (19")
- Mouse/Keyboard : Logitech Cordless Desktop MX3100
- Wifi router : Linksys WRT54GS with SpeedBooster
- Wifi PCMCIA card (for the laptop) : Linksys WPC54GS with SpeedBooster

Composants :
- BareBox : Textorm 69U6
