Uhm if you going to buy hardware it is worth to thing about sun x86
flavor servers (I'm really enjoy my two x4150 connected via FC to an sun
stk 2540), furthermore it is really easy to install Nevada Comunity
Express (currently I use build 97). Furthermore Sun XVM Server will be
free of charge even in productive use and will be shipped (fully
available as free download on suns homepage) with PV drivers for
windows, so it may be the most comfortable choice. Especially with two
equal servers you could reduce downtimes and additionally enterprise
level support contracts are possible depending what you'd like to do.
