Two of my daily used computers are built in Fractal Design cases. I have the larger Arc Midi for a gamming rig, and the Define Mini for my surfing general purpose rig.
I like the the Arc Midi is a mid size tower that supports full size ATX mobos plus large 240mm Radiator like the H100. or large size CPU cooler. . The Define Mini is mATX/Mini ITX. Has the door, which I don't mind. The usb's are on top. I rarely have to access the Optical drive.
Fractal Design - Arc Midi - MSI Z77-GD65 - 4 x 4G 2133 Gskill, GTX 680 Evga SC+, *under powered* Seasonsic 460W Fanless PSU. 2- Crucial m4 SSD 128Gigs In Raid 0, Blu-ray Burner. - for an easy build this computer is Fast. *** . I was worried the PSU wouldn't hold up, but the GTX 680 only uses about 50w more power than my previous GTX 560 ti. And the total power at full load is around 240 watts, normal game play is less than 200 watts total. I've stress tested the computer and it remains cool enough and doesn't skip a beat. It does make some noise with the H100's stock fans at 100% and the 3 Arc Midi fans at 100%. But i don't mind the noise with game music going over sound system or with headphones. True water cooling would be nice maybe a winter project.
Fractal Design - Define Mini - MSI Z77 mAtx, i7-3770S - 65 watt TDP with HD 4000 graphics. 8 gigs 1600Mhz Gskill, 1 Crucial 512G SSD, 2 TB HD, Seasonic 400w fanless. Zalman low profile cpu cooler. (didn't need low profile, it was a leftover cooler i had avalable at the time.). Blu-ray burner, wacom tablet.
Each computer is connected to an Asus 27" monitor.
With the Arc Midi turned off, You start to appreciate a quiet computer build like the Define Mini. It does its job surfing and playing light games like SC2 etc. I may add a GTX 660 when they are released later in the year. But I don't really need the graphics speed on this computer.
The Zalman cooler fan is actually noticable when it spins up keeping the 3770S cool under stress. I may go with a larger passive cpu heatsink and remove the 2TB drive, and make this computer near silent.
I tryed using the 3770S in a smaller SFF case, but under stress it was getting too hot for the passive heatpipe cooling.
My Arc Midi can be rode hard and keeps cool. Played around with overclocking, its fun but isn't needed for my needs.
