I was wondering what the advantages or disadvantages of using either package in a home environment might be given the release of Windows 7. I currently have W7 64 bit Ultimate installed on my Desktop PC, Home Theatre PC, and Laptop...While my girlfriend has Vista 64 Home Premium on her Desktop PC, XP Home SP3 on her laptop and on her other desktop. I am building a box with use as a server in mind (4 gB RAM,2 TB storage) and am curious as to what would be best to run the whole setup with. A few things to consider are: 1) How much overhead does Server 2008 R2 require? Is it configurable/scalable down to home usage requirements or is it just a monster designed for server farms? 2) Windows Home Server is 32 bit and built on Server 2003 (kinda...lol) but has it's own SP3 coming out soon that is supposed to enhance its compatibility with W7 etc.,etc...Should I go for that or wait and see if MS does a rebuild of WHS based on Server 2008 R2 or something? 3) Could anyone PM me a link to an ISO of WHS to experiment with please? Any advice is greatly appreciated!
