The GOPC doesn’t’ have a processor, RAM, a HDD or an optical drive, so the following are required in order to assemble the GOPC.

• Intel Pentium 4 'C' 800 MHz Hyperthreading 2.4 GHz CPU
• 512 MB (2x256 MB) Crucial DDR400 RAM
• Maxtor DiamondMax 9 80 GB hard drive with 8 MB cache
• Sony CRX225E 52x24x52 CD Burner

The instructions seemed to be thin and fat on information. Though the information provided is good enough to find out things with some trial and error, but as there is a set method of fixing parts, one can’t feel like fixing a jigsaw puzzle. And even, some may find while building a computer that making a mistake can’t be noticed is early stages, therefore many might have to rebuild the PC from the starting.

For instance, the heat sink clips and the slot don’t provide any clues about how to how to insert the clips, nor do the say how to insert the heat will face. It is simple to try each wrong combination of arranging the heatsink and clamping it down. It is also simple to insert a HDD the other way, as the instructions don't even say that the cable offered is not long enough to handle the case where the hard drive's pins are on the other side.

To install an optical drive, a plate that occupies the socket requires to be taken out. While this step is common for all PC cases, the GOPC has a screw that is at the back side of the card reader and is hard to take out or change. Those with general screwdrivers will have a difficult time taking it out, and a recommendation would be to change that screw with a thumbscrew so that the user will not have to force a Philips screwdriver in there.

To reach certain parts of the GOPC, stable hands are required. Installing the memory is difficult as hands have to reach out for the banks from outside the case. And also, the memory sits next to the floppy connector and the primary IDE connector.

If planning to install a video card to replace the included SiS video card, the card's size plays a vital role. An ASUS Radeon 9600XT card hardly sits inside the socket, and all the cabling for the floppy drive and the card reader had to be removed from the way and in the heat sink and HDD. The heat sink on the video card is tiny, and it didn't require any additional molex connectors to run it. The 220 W power supplies only have enough molex connectors to power 1 HDD, a floppy drive, an optical drive, and the motherboard. Expansion video cards that require a molex connector should be skipped for this computer on its own.

The most difficult part of building the PC is the heatsink. This is because the clips provided by the Vantec Aeroflow, is in 1 piece and easy to install.

Gigabyte should be given some credit though for designing all the cabling to fit only to a specific set of pins. It's likely to make a mistake wiring the parts together. And somehow, everything fits.

The GOPC might be small in size but is very useful after completing the assembling.
