I agree, Lekta, the Silverprop is a sweet Graphics block. I seriously considered ordering it, but that would have meant yet another store and shipping charge, since it doesn't seem to be as available as the Swiftech (in the states at least). That, plus the mcw50 is 25 bucks cheaper
I actually just got my first package of parts today! The swiftech blocks look great, they're bigger than they look on the web

The BI Pro II is bigger than I thought, too. It's an inch longer than hwlabs claims on their website, and I'm not sure I can fit it in the front bays without serious modification.
I hope that Dremel gets here tomorrow!
Thanks again for all your input.
