The inside is very roomy and allows you to install even the largest ATX complaint motherboards. I used the Chaintech 9CJS ZENITH
for testing, this is about the largest motherboard I’ve come across it fits inside nicely. When we start adding components however we quickly see the available space disappear and it starts looking cramped:Chaintech 9CJS Zentih
P4 2.4 “C”
Swiftech MCX478-V + Coolink 80mm 4500rpm fan
2x Corsair PC4400
PNY Geforce 4 Ti4600
Maxtor 80GB Sata
Nec 4x DVD+/-RW
To further reduce noise Antec preinstall rubber grommets in the HDD enclosure and helps reduce the vibration of your HDD’s:
The PSU has a large bundle of connectors available, among those we have a couple of 4-pin connectors marked “FAN only”, these connectors provide a lower voltage than the default 12V and it will make your FAN run slower, producing less noise, but also less air movement. The FAN provided with the Overture is sitting in the back in a spot measuring 92mmx92mm. It draws power from a normal 4-pin connector and depends on a small thermal sensor to determine its speed. The sensor is preferable placed close to a heat source if you want to the fan to operate efficiently.
In a cramped desktop case rounded cables a really a necessity, Antec provided some machine manufactured Cobra Rounded ATA and Floppy Cables to improve airflow.
Wrapped with nylon mesh for maximum air flow improvement
40-pin 80-conductor cable, ATA133/100/66/33 compliant for high speed data transfer (A26 IDE cable)
Highly flexible 26" round cable (16" + 10") with two device connections, one motherboard connector.
Shielded with aluminium foil and braided silver mesh with ground, for maximum shielding
So with system neatly installed inside, it is time to close the cover and hook it up ->
