These would make very powerful thin clients. That's not a criticism, just an observation that you could possibly get more bang for your buck using them in a diskless workstation mode (ie so they run the programs themselves). However, as far as I'm aware Edubuntu doesn't yet support this mode of operation directly so it might be a bit of a technical challenge at present to go that route. > I want to implement Ubuntu thin client for the lab to simplify > management, configuration, software distribution, anti-virus fight. etc. > etc. Could someone suggest what CPU and what size of RAM, Hard disk > would we need for the Server machine for the 30 computers. I'd say you want to think in terms of a few things, roughly in order or priority: 1. Fault Tolerance -- use RAID 1 or 5 if at all possible. If/when a disk fails, you probably cannot afford to have all 30 thin clients die with it. 2. As much RAM as possible. On a 32-Bit system, you can get 3-4GB. I'd suggest at least 3GB if you can afford it. 3. SCSI disks if at all possible. They're supposed to be considerably better with multiple users. 4. Possibly 2 cpus -- 3GB RAM first though. Don't skimp on quality when it comes to your thin client server. It's such an important component that buying an unreliable one is just not worth it. Just think what happens if it goes down. Our thin client server is currently very under-used (usually about 5-8 users at a time). It's a dual 3GHz Intel Xeon with 4GB RAM, 2x 75GB SCSI disks in software RAID1. I hope to get it to take 30-40 users concurrently.
