This system case has only one place for an external 3.5” device, although the chassis could have accommodated two. That’s because there’s no second bay for the second device in the front panel.

Hard drives are fastened in this case in the classical way, i.e. with four screws.

The mainboard is installed on a metal plate that consists of two parts riveted to the chassis, and is fastened with screws in nine points. The screws are already in place. The fact that the plate is divided in two ensures an additional airflow to the back side of the mainboard for better cooling.

There are seven slots for expansion cards at the rear panel of the case. They are covered with single-use brackets. The expansion cards can be fastened with screws or with a special bar:

But brackets with additional connectors shouldn’t be fastened with this bar; such brackets will be just hanging about loosely since they are not firmly connected to the mainboard.

The back panel carries an 80mm fan. There are mounting holes there for the installation of a bigger, 92mm fan.

This system case is equipped with an ISO-400PP power supply with a specified wattage of 300W. The PSU offers four Molex connectors (for HDDs and optical drives) and two mini-plugs (for floppy drives). There’s a power switch at the back of the PSU, but there’s no additional connector to power up the monitor. The power cables are all long enough as to cause no problems during the assembly.

And here are the temperatures of the subsystems of the computer in the TLA-570 system case:
