From MythTV Official Wiki
Notes while designing and building my "nauhuri" MythTV box
- case max width 410 mm
- old 3.5" HD fits inside the case
- old Hauppauge Nova-T 500 dual DVB-T tuner card fits inside the case
- silent, low power consumption, 1080p capable and all that
User:Trogod/System0 looks like an excellent resource especially on motherboards with an HDMI port.
