I looking to put together a few Catagory 2 servers, has decribed in the MAS 6000 Technician Handbook 6.0. Using the mail server, gateway, samba, and webserver functions for a small network with a max of 20 Windows clients. The tech manual list a 400Mhz Pentium 2 or better with at least 128MB of RAM for that type of usage. I think I'll do a little better than that because it's pretty cheap anyway. More like 1Ghz or better CPU and 256MB of DDR
Anyone have any ideas for a currently available motherboard platform for a lower end server? I've worked with a lot of MSI and Asus boards in the past, particularly the AMD via chipset models. It doesn't have to be an AMD platform, but I always liked the price.

Any suggestions for something appropriate that will install wihtout any nonsense and be supported by the OEM for at least the rest of the year?
