Servers are the most efficient computers available. Most of them are designed for fast data processing and transmitting, and not for gaming. Even if a server has a graphics card (not necessary in all situations) it’s a very slow one, on-board with 8-32MB of memory, enough for displaying statistics and diagnostic data. Their hard disks on the other hand are very fast, usually 10,000 or 15,000RPM, for very fast and dependable data access. Their memory modules are also different from desktops, they need to be very reliable, meaning that ECC (error correction cycle) RAM is mandatory. For even faster data access, servers also need huge quantities of memory, server motherboard usually support up to 32 memory modules, 4GB each.

Because servers don’t really need monitors, especially if they are used in groups of 4-128, special computer cases were designed for them called Racks, which come in many different sizes for different destinations. For every such server group it’s sufficient to have one keyboard and one monitor, so a manufacturer called NORCO designed a very special, laptop-like monitor and keyboard that slides in one of the server rack bays, thus saving a lot of space. It doesn’t require any software, the server administrator selects the server unit he wishes to control from a simple on-screen menu, so it’s a very reliable server computer accessory.
Another useful server computer accessory is a special 3.5” hard disk rack that houses two removable 2.5” hard disks. This can be used for lowering hard disk cost by using two 2.5 7200RPM drives instead of one 15000RPM drive, or to improve speed by using two SSDs instead of one 3.5” high-rpm noisy hard drive. It’s made of aluminum and plastic, for optimal cost and durability. For data two S-ATA cables are needed, one for each hard drive, but only one power cable is required, because 2.5” drives have very low power requirements. It also has LED indicators for both power and HDD access, and a practical security lock prevents accidental removal of drives.
To bring down cost even more, RAIDON designed a very useful memory card to S-ATA rack. It fits into a 2.5” hard drive bay and uses to Compact Flash memory cards in RAID 1 or NRAID mode. This is not exclusively a server computer accessory, it also fits into any S-ATA laptop drive bay, improving both performance and battery life. For only $35 + cost of CF cards you can upgrade any S-ATA compatible computer’s hard drive to server-like speed. One of the cheapest and most useful computer accessories is a 5.25” to 3.5” bay converter. Basically it made of 4 pieces of metal and 4 pieces of rubber. One part has to be mounted to the side of the 5.25” bay, and the other one that’s connected with screws (but separated by pieces of anti-vibration rubber) has to be mounted on the 3.5” hard drive. The procedure is the same for the other side too. It costs only $6, but spares you a lot of stress and headaches normally caused by loud variable noises.
