If you want a fast, single-core processor, the Pentium 4 3.8 GHz can be found on eBay. It uses a LGA775 socket, so the motherboard can be upgraded to a Core 2 Duo or Core 2 Quad (but not Core i7) in the future, if the programs you run ever get upgraded to take advantage of multiple cores, or if you want to run multiple sing-threaded programs concurrently. Once you decide on the socket type (in this case LGA775), then it just comes down to what other features you want on a motherboard, and buying one from one of the major brands (Asus, Gigabyte, etc) that matches your feature list and budget. Any LGA775 board you buy will have multiple SATA connectors on it. They usually have fake RAID, but I don't recommend you use it. Instead, use Linux software RAID. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
