WxHxD: 200x326x260mm, tiny, limited CPU cooler height, 2x USB 3.0 with external header, Lian Li has an adapter to convert to internal headers. Officially mini ITX only, mATX boards fit if they are less than 220mm deep
, i.e.MSI H67MA-E35, all mATX Z68 boards are 246mm deep. To fit mATX, the HDD tray has to be removed. I use this case with an older S775 mATX board.
All cases except the Antec accept a standard ATX PSU. Take a look at the recommended PSU list
, in short Seasonic X-Series, Enermax Modu/Pro 82+/87+, Nexus NX Series, in that order.
Mini ITX cubes like Silverstone SG05
or the bigger SG07
could work, too. Neither one has USB 3.0. Both come with a PSU but neither PSU is really quiet.
I would use the Q-11, Zotac Z68-ITX WiFi mainboard, a Scythe Big Shuriken heatsink and an Enermax MODU87+ 500W or Seasonic X-560 whichever is cheaper. The MSI 560 Twin Frozr won't fit, but a Gainward GTX 560 Phantom will
, since the PCB is shorter. The heatsink is pretty good if it's still too loud you could disconnect the fan and strap a 120mm fan on, no warranty voided. You can use a 120x25mm PWM fan
on the Big Shuriken to lower the noise level even more. Just remember to mount it in a pushing air from the heatsink so it doesn't work against the PSU's fan.
