Has anyone actually grabbed the iso/whatever is used by the web setup?

I tried the web setup, and depending on the option you choose initially, you seem to get a different set of files unpacked. I accidentally chose the wrong option, and the setup locked me into an upgrade. It created a folder called WindowsESD, with all the install files there. I ended up just downloading an ISO and using that instead.

My mouse is laging in virtual box...

Of note; Aero glass seems to be COMPLETELY GONE in Server. No "Desktop Experience" feature to add like in R2 and previous versions. You can't even change the window colours and only get Aero Basic or the high contrast themes. Attempting to use the Appearance settings simply gets you a "Not available in this edition of Windows." message.
Themes on and all the rest - it really seems to be gone.

Alright, this time I downloaded the 32-bit version and the SHA1 hash was fine, but still recieve the <ProductKey> error...

I actually just had this happen with a Server dvd burned yesterday that I knew to be fine. Strangely switching to a different DVD drive solved it. I had been using the same USB burner that made the DVD in the first place - a drive that works *perfectly* otherwise, I might add - and used an old 360 HD-DVD drive instead. So more than likely if the hash matches and it burned fine - the drive is the issue.

@DeFacto
If installing in VMware, when selecting the iso when setting up the VM, choose "I will install the operating system later" in order to avoid Easy Install.
That means, don't specify installer disk/iso when creating the VM. Select Windows 7 (or Windows 7 x64) as guest OS and go on with the wizard. After powering on it, mount the iso manually (and reboot).
Hope this will work.

Thanks.Now the size small then WDP.I like it.

I have a copy w/ its own key too.
Its a bit smaller than the linked page x86 .iso.

It works in Virtual Box but there is no internet connection

Everything works for me

It works for me now as well.
