Motherboard and Cable Routing

By now, you know that the TJ-07 is divided into two main chambers cooled independently of the other. The top portion holds the motherboard, expansion cards, and optical drives, and the bottom holds the power supply and hard drives. The bottom chamber is at least partly subdivided into three other chambers: One for the power supply and two more for each of the drive bays.

Divide and conquer: Individual components are separated as much as possible so that each can be cooled without dealing with heat from elsewhere in the system.

Installation begins with removing side panels. SilverStone has tried to make things as easy as possible by using thumbscrews, but because they all screw directly into the aluminum frame, they frequently stick and bind, which makes them difficult to remove by hand. Often, a screwdriver was needed to generate enough torque to remove them smoothly. Steel bushings for the thumbscrews would have made things much easier.

All the thumbscrews tend to bind in the aluminum frame.

The sheer size makes the case fairly easy to work in. A removable motherboard tray allows the motherboard and the expansion cards to be put together outside the case where there is plenty of room to work. This is probably most helpful for large Extended ATX and SSI motherboards, which may be tight even in the TJ-07. Note that the motherboard tray slides into tracks, but there's no way to tighten the tray to the tracks; the tray is secured only on the back panel, with six thumbscrews. There is potential for rattling between the motherboard tray and the tracks it fits into.

For regular ATX boards, it's probably not worth going to the trouble of removing the tray and installing things separately. Removing and replacing the tray is more trouble that it looks, because the aluminum guide rails have a tendency to stick, especially when a heavy motherboard is installed on it. As with the side panels, the thumbscrews often bind in the aluminum frame.

Besides, there's another reason to leave the tray in the case during installation. The motherboard standoffs are very tall, leaving plenty of room to hide cables — even the thick bundle of cables for the ATX power header. With some careful planning, all of the cables in the system can be routed beneath the motherboard to keep the main chamber uncluttered. However, if the motherboard tray is removed from the case, it is impossible to run power cables in this way unless a power supply with detachable cables is used. The cables must be routed from the bottom chamber before the motherboard is screwed down. If the tray is removed, it is too far from the bottom chamber for the power cables to reach.

Four fans provide a lot of airflow around the top half of the motherboard.

The motherboard tray is removable, but there are reasons to leave it in place during installation.

Cables between the top and bottom chambers are routed through these holes.

Motherboard tray completely removed.

Tracks for the motherboard tray: There is no way to lock the tray into its tracks.
The motherboard tray can be easily rattled in its tracks even with all six back thumbscrews tight.
