Hi, I just wanted to share my out of the box experience so far with eracks.com and their studio machine pre-configured with 64 Studio, the 64 bit version.  After some video mismatch solved, I was then able to select my MultifaceII in qjackcontrol on HW:01, run ardour and connect with 1.5 ms latency.  I then extracted some lossless audio from CD using the included soundjuicer utility and am now auditioning ardour at 1.5 ms, just playback for now.

After getting the box in the mail, I opened it, dropped in my HDSPe PCIe card and that's it so far for configuration.  The HDSP mixer also included in 64 studio worked first try.

If anyone is interested here are the machine stats:

eRacks.com rack studio case, blue faceplate
64 Studio 64 Bit Realtime Pre-emption Kernel(SMP)
3 gHz Intel Core 2 Duo, 1.3gHz FSB, 4gb Ram
2X500gb Seagate Barracuda 7200 RPM
RME HDSPe PCIe Host card

That will go into:
6U L&M custom shockmount case
1U Furman Power Supply
MultifaceII / Glyph Drive Bay
1U LCD Display/keyboard/trackpad
3U rack pc

And a big sticker of TUX on the outside of the case.
