Basically... buy Xeon || AMD two way boxes. Be boring, look at Dell or penguin computing or something. Dont bother with 64 bit. Think about that in about 2 years time. It will irritate you in 2 months after you buy it, *i promise*. Dont buy from some indy very cheap manufacturer, cause, if the nodes will fail, you will be left waiting... or make them give you a decent guarantee. Or a big box of bits. Look at the price of the chip : speed ratio. This graph will have an inflection point, at which more money input gives diminishing returns speed-wise. Buy at this inflection point. This changes all the time... of course. There is no point in buying the *best* out there right this second. Just buy a little behind it, and buy an extra box or two. Find out what you want to run. Buy as enough memory so it doesn't thrash your disks. (Or just fill it with memory). Spending about 2 grand (USD) on them a piece (I dont know what that is in Lira) should buy you something decent operating at 3 gigs, with a couple of gigs ram. Then have a look at http://bioinformatics.org/biobrew/ www.rocksclusters.org/ Sorry if this is very uninspiring/boring advice... its just, you want to keep everything as simple as you can. There will be tricky bits no matter how simple you make everything. Good luck. Philip.
