Some computer equipment models (the HP LaserJet 4 is one) are just plain workhorses; and you have to ?pry? them from their loyal owners? ?cold dead fingers.? One such workhorse is the Cobalt RAQ, a line of rackmount servers. It can be used in server farms for ISPs or businesses or by hobbyists as, for example, an email server.
Sun Microsystems purchased Cobalt and in 2007 discontinued and stopped supporting the RAQ line--the RAQ still has an enormous installed base and a community of diehard supporters who maintain several versions of open-source operating systems for RAQ servers, especially the x86-based RAQ 550. So if you?re a network admin running RAQs or a seasoned hobbyist on a budget, the RAQ can be an excellent way to go. It is an excellent server to learn on, there are tons of RAQ specialists on the tech boards, and used units can be found by the hundreds on eBay for well under £100, which is impossible to do with any other rackmount server of comparable quality and reliability.
