Don't get me wrong but you seem totally clueless as to what a bladeserver is and what it's used for. I looked at a few other posts made by you. Especially this post. Did you miss SDK's post? He wasn't kidding when he asked if you had $50.000 to spare.
Build a plane old PC and be done with it. Anything more is just a waste of money. Hell, if you've got that much money to spend why not build 2 PC's and network them. Use one for your programming/games and the other as a fileserver/webserver/whatever.
Experience is something you don't get until just after you need it.
What would you want a blade server for? It seems a bit exotic (and expensive) for a private individual?
I could be wrong, but I tend to associate them with a clustering type of technology and with one application per blade. I think that might be a bit cumbersome in a SOHO/domestic environment?.
If you cannot do someone any good: don't do them any harm....
As long as you did this to one of these, the least of my little ones............you did it unto Me.
