My son wanted a gaming computer but is in school on the other side of the US. So I was looking for a way to build a capable little machine that would be small enough to pass the stringent carry-on requirements for air travel. I also wanted it to be silent.
I stumbled across the Cooler Master Elite 360 case because Fry's was blowing them out for only $25. This is a very clever design that manages to pack a mini-ATX motherboard into a very small case. The obvious trade-off is assembly complexity, but here is a comparison with the Antec Solo:
Here are the left and right sides:
The Thermalright AXP-140 and 140mm SilentX fan handle most of the cooling, with help from a simple foam duct made from the AXP-140 packaging and toothpicks.
Overall this works *extremely* well. The only problem I initially had was that I let the motherboard throttle the CPU fan, which then did not pump enough air to the rest of the case. But at a steady 900 RPM, the CPU & GPU temps stay well below stock, even with OCCT &/or FurMark test runs.
The main HDD is a WD640 Blue, but I also included two small laptop drives for built-in backup targets, in combination with SyncBack SE. This seems prudent for a case that is going to get moved a fair bit.
Getting the cooler on the HD5770 was actually the hardest part. See this thread:
