I built a system for a friend with this case a couple of months ago. Actually, I simply cloned my own PC, but in a black chassis (I'm one of the lucky few still got a P150). He was amazed by how quiet my computer was and how powerful, even overclocked, it was still silent.
I find the case a GREAT evolution of the SOLO/P150. I would gladly buy one if there were a glossy white version like the P150 was. We should spam Mike Chin to get a P150 II SPCR White Limited Edition!!! (P180 SPCR Black Limited Edition back in 2007, had bought one on day 1). We should make a poll about this!
In the meantime, I've modded my P150 by removing the HDD cage and cutting the back panel so that I could change easily my CPU heatsink without full disassembly. But that was for LGA775, when I upgraded to LGA1155, I was pissed that the socket wasn't aligned with the old one, didn't go to the trouble to cut the steel again with my Dremel.
I've also removed the reinforcing bar of the chassis that ws always in the way when needing to remove PSU. See pictures below.
For whatever reason, ImageShack rotate my picture like a retard.
Anyways, back on SOLO II:
Like others have said, I find questinnable the paint quality for this case. My P150 white does not have this low quality paint problem with the screws. I don't even tighter the side panels screws on my friend SOLO II and the paint goes off.
I've also encountered problems with the mounting of the 5.25 bays. My friend didn't had an optical drive, but he had a Startech HSB100SATBK: http://ca.startech.com/HDD/Mobile-Racks ... SB100SATBK
The width of the bays are slightly larger than they should, so using the rails wouldn't work correctly with the Startech HSB100SATBK. With an optical drive I think it could have worked still well enough, but with the Startech product, If you look at the picture below, you'll understand that the design of the HSB100SATBK makes it difficult to install on this case .
I had to fill the spaces between the mounting brackets attached to the HSB100SATBK, because the way the swap bay is designed, it is only attached to the "main harddrive bay" by 2 screws in grommets(for less vibration I presume).
So by design, the HSB100SATBK sides will fold inwardly around the top edges. With the slightly larger 5.25 bays of the SOLO II, the rails would simply get off the tracks. On one of the side of the HSB100SATBK, there's the eject mecanism that connects to the front door of this swap-tray. It was an even harder job to fill the free spaces to make sure I wouldn't interfere wit the eject mechanism.
With the spaces filled, the sides would go outward instead of inward. I had to use several layers of cardboard on each sides to fill the spaces.
Another complain I have with the SOLO II, but it is mostly with the design of the USB3.0 internal connector, so not a SOLO II specific. The USB3.0 internal connector is HUGE. The cable is heavier than the connector itself, so once pluggued in the USB3.0 headers at mid-board, the cable could disconnect overtime just by the weight of the cable pulling away the connector. Compared to USB2.0 connectors, I find that this design has major flaws..
Even worse, most motherboard USB3.0 mid-board header are right next to the ATX 24-pins power connector, so cable management is a real pain with such big and heavy cables. They do not bend/fold/curv that easily.
Other than that, I find the SOLO II a great case. I actually found the stock Antec TrueQuiet fans (at low speed) quite good. But I already had ordered the Nexus 120mm for my friend, so the Nexus went in. I agree that at the pricetag of the SOLO II, Antec should have included a front intake True Quiet fan too.
I would strongly suggest to not use the PCI-slot bracket that comes with the SOLO II. Those bracket just let tons of dust gets in your case. I've upgraded mines for the Nexus PCI-300, and I no longer have any dust in my case, I need to clean them once a month since they'll get full of dust, like the fan filters at the front. This means that the video card fan is strong enough to suck the air inwardly from the back of the case. I would also strongly suggect to close the "honneycomb" section to prevent dust from coming in.
With the Nexus 120mm silicon mounting strip, I did not experience that Bar81 experienced with the space between the filter and the case being too close.
