I just wanted to thank everyone for all their input. Seriously, although I questioned a lot of the contributions they were all valuable even if only as pointers in the direction of a previously unknown or unusual vendor, or to consider options that I had not previously thought of.
Pending a store visit to put my sweaty hands on one of these creatures, I'm probably going to settle on the Cooler Master Mystique 631 (
RC-631-KKN1-GP, or perhaps
RC-631-SSN1-GP if I decide on the silver finish).
Allow me to share some of my decision process...
I ended up looking for cases with or without power supplies because the "extra expense" of cheap PSUs didn't matter, and I could always use a spare for the parts stockpile. Although in the end it did not matter, it did open up the possibilities.
I was forced to completely give up on the removeable motherboard tray.
I stuck to my guns on everything else, but placing importance on 120mm fan
openings more than the fans themselves, since it's likely that I'll be replacing any included fans with Arctic Cooling's new PWM PST fans the day they hit the streets, if not some S-FDB units instead.
An extra requirement popped up while I was searching, which was room for four hard drives in front of the front intake, since I've decided to play with RAID 0+1/10. This knocked the Thermaltake Matrix VX out of the running, as well as the very lovely and professional looking Lian Li PC-16B.
I decided that all the Cooler Master Stacker models were too large - too deep in particular - and would end up sticking out like a sore thumb from under my modular furniture system.
I also decided mid-stream that a vented side panel would be a Good Idea, which was another strike against the Lian Li and also knocked out the Antec P160. This factor also takes out the otherwise very solid, tempting Thermaltake Soprano.
I was still tempted to opt for that Rosewill R5601-BK but decided to spring for a case with slightly better fit 'n finish.
I also decided that the transverse drive mounting on the Mystique is a good thing since it allows more room for today's immense video cards. The Antec P160 shares this feature, so if I end up deciding that the Mystique is no great case then plan B is to get an Antec P160 and drill out the left case side for a TAC pattern and a filter.
Oh yeah, and I haven't ruled out the possibility of cutting extra slots into the lower front facade of the Mystique!
Thanks again everyone for all the help!
