Soo.... it's built! Unfortunately I left my camera at home so I'm not able to upload pics at this time, but I do have some information to report, and some questions to be asked...
First, some observations: Silence is awesome... I almost didn't want to put the 7750 in because I knew that no matter how quiet it was, it was going to ruin the complete silence of when it was fanless, LOL. Also, Intel HD 4000 is surprisingly capable for light gaming. The two SSDs in RAID0 are insanely fast... I haven't had the opportunity to benchmark them yet to see if I'm getting ~1GB/sec speeds, but just clicking around Windows was almost fun just because everything was so fast it was messing with my brain. Note that this could probably be the same experience I would've had with just a single drive on SATA3. I had one of the SSD's on my 'old' build but only running at SATA1 speeds. Windows definitely boots incredibly fast, as has been reported by other ASRock Z77E-ITX users, although since I'm running in RAID, there are a few extra seconds during POST for the RAID controller. The heatsink side of the case only gets mildly warm to the touch even when gaming. I did not run anything for a long period of time though, so I will have to try again after a good gaming or benchmarking session.
Some performance pics I snapped with my phone. These were taken while running Half-Life 2: Lost Coast benchmark at max detail. I think resolution was 1600x900 in windowed mode. I ran Crysis at max detail in the same resolution and windowed, and the results were very similar. Also this is 'with' the 7750 installed. The system idles around 31c-35c and about 30w. Ambient temperature is 25c.
These temps are acceptable to me... the problem lies in running Prime95, which hit 100c in seconds. Obviously there are limitations due to the passive nature of the case, but I'd like some insight on whether you all think this is just 'what it is' or if improvements can be made without adding fans into the mix (which would defeat the purpose). This was also my first time ever using Prime95... could it just be User Error? LOL
Also, the 4-pin Pico-PSU connector does not fit in the provided hole in the case. The single 'pin' connector fits fine, but my 192w adapter uses the 4-pin, so I'm at a loss on what to do. I figure I need to make the hole larger, as well as put in two holes for the mounting screws, but not sure if that's something easily done with just a dremel, or what.
One last thing, the Wi-Fi seems to be acting up. It appeared to be working fine while I was at work (where I put it together) but when I got home at first I was getting terrible download speeds (30-50kbps). I tried messing with the antennae a bit, and the situation reversed, download speeds went up (although not quite as high as they should be) and upload speeds went into the toilet. My guess is maybe the internal Wi-Fi connection is 'shorting' or something?... I'll have to look at it later.
Hoping to get some additional benchmarks done later tonight, and maybe some pics as well.Edited by SpyderMS - 10/21/12 at 9:59am
