Hang on a minute...
If you want a monitor on a WHS - then you can have one. Its only Sever 2003 with some mods, for gods sake.
WHS Treats my USB drives just fine, thanks for asking.
WHS doesn`t officially support any type of RAID set, although some run raid 1 on the system drive. Drive Extender tries to solve a different problem in a different way. You can`t really compare.
And if you want to run applications on it, then you`ve quite mad.
Its not rocket science mate.
And for the record, my whs has never locked up in 18 months. Only time it breaks is when I break it ;-)
People who moan about WHS generally either don`t understand what it is, or are just trolling.
