Actually they are both more like the BQE series (SLK3700bqe, SLK2650bqe). They are definitely not Performance series cases. Nice that they turned the HD cage to the proper directon in the big one. The both have the vibe bushings for the HDs. The big one looks like they have the drawer type drive mounts like the Sonata and 3700BQE.
. The SLK3000-B is more like an OEM version for system integrators and VARs or hobbyist builders - it doesn't even have users' guide in the box - you have to DL it if you want one. I'm wondering if they'll make a similar version of one of those. We'll probably have to wait until the channel ls cleared of most of the 3000-B ($31.+sh at provantage). But it looks like Antec left off the 3.5" drive bays on the big one - big mistake IMO as lots of add-ons fit in those. I'm sure that decision will nip them on the arse... It looks like it would be considerably less expensive to make the 3000-B than the NSK6500, so maybe they'll keep on making it.
. If you want a similar case to the NSK6500 w/o PSU now, the Evercase/Ever Case/AMS EC-4292 or GC-4292 is it!
