I want to build three desktops/servers entirely out of recycled/used PC parts. Naturally I want them to approach silence or generally inaudibility. I have some experience assembling computers from components. I'm really looking for brainstorming as to what would be optimal in my situation.
My other requirements for all three systems are:
*Low power: use as few watts, especially at idle, as possible
*100% ROHS compliant. They can't have lead in the solder.
*Libre drivers in Linux/BSD for all components; no binary blobs
*Prefer coreboot compatibility for mainboards ( so one of these motherboards http://www.coreboot.org/Supported_Motherboards
*Prefer X86 or compatible architecture, just because the Linux/BSD support is better for them. ARM, MIPS and POWERPC is an option for PC1 but not PC2 or PC3.
PC 1: Offline desktop
It would run Gnome 2 and Evince as its most demanding applications, all other applications are lightweight. Will run Linux and needs minimal local storage. Needs an optical drive
PC 2: Internet Browsing device
Needs to be powerful enough to run Firefox, but not more. Would have OpenBSD as its OS, so hardware should be OpenBSD compatible.
PC3: Network (file)server
Administered from the command line, very low computing resources needed. Will also run OpenBSD. 128Mb RAM and 80GB HD would be plenty
Would run 24/7/365 (doesn't need remote administration), so lowest possible power is desirable. I was thinking about an alix device for this, but it would have to be a used one not a new one; in case anyone has any experience with these, I'd appreciate your comments.
My overall budget for all 3 is about $1500 but if that's not enough, I could go higher.
