My business runs on a Linux server (Suse Linux), which is very stable. It also saves a lot of money on licences since we use Suse Linux Email Server 3.1, which is browser based. Our desk top pcs run windows 98SE, but the server copes nicely with MS Office etc. Also, you find that virus writers dont seem to write them for Linux (yet anyway), so it is secure. The system you mention sounds like good value.
