Computer Tower Cases

Alien Computer Cases Aren't That Alien (they are made for Gaming Systems)

Computer tower cases are a popular style; wholesale computer cases, Antec computer cases, Alien computer cases and more. A case is important to the lifespan of your computer by enabling effective airflow.

By far, the most popular cases are computer tower cases. They are the easiest to work in, because of the room, and they are easy to place under a computer desk. When you are getting ready to purchase a computer case, here are a few things that you should take into consideration.


The airflow of a case is extremely important to the life of your computer. Poor airflow will trap heat inside the case which will reduce the life of your components. This is especially important in gaming computers, as the higher end components they use will produce more heat. Things you should take into consideration for good airflow:Computer Airflow

  • Case Fan Placement - The location and orientation of case fans is the best way to ensure good airflow. The best setup of computer tower cases will include fans that both pull air into the case, and exhaust air out. Higher end cases will have anywhere from 1 to 3 fans on the front of the case that pull fresh air into the case. These fans will typically blow over the hard drives and optical drives and force the air into the interior of the case. Along the back of the case will be the exhaust fans that pull air from inside the case and exhaust it out the back. Some computer tower cases will even include an exhaust fan on the top of the case.
  • Component Placement - The location of components can have an effect on the airflow of your case. For maximum cooling, you want the air that is pulled in from the front of the case to blow over your hard drives, flow through the middle of the case, and out the back. Expansion cards such as graphics cards, and sound cards can block airflow in the case, so careful positioning of these components and the fans is important to good airflow.
  • Cabling - Keeping your cables neat inside the case will help with proper airflow. A mess of cables in the middle of the case will interrupt the airflow of the case and help to trap heat inside. There are a few things you can do to help this. Routing your cables along the edges of the case and keeping them out of the center helps keep the middle free of obstructions. Using round cables instead of flat ones for any IDE drives will also help to keep air flowing through the case.

For a home office computer, you may not need a full tower case, and can go with a smaller form factor such as mini-ATX or micro-ATX. With smaller form factors, you can go with a smaller case.

For gaming computers however, you will need to ensure that you have room for a few different components. As part of a gaming system, Alien computer cases have received some favorable feedback from gamers.

Graphics cards can measure as much as 12 inches long, so you will need to ensure enough room from front to back, keeping in mind that the drive bays will also take up room in the front. If you are planning to use an aftermarket heatsink for improved CPU cooling, you'll want to ensure that you have enough room from side to side. Some heatsinks can get quite tall, and you may need as much as 8 inches of clearance from the top of the motherboard.

If you will be installing multiple drives, make sure that you have enough drive bays to install them all. You will also want to take into consideration room for running your cables. Some computer tower cases will include room behind the motherboard to run cables to the various locations within the case.

For gaming computers, take into consideration the placement of the fan mounting locations. You will want to make sure that you have enough locations, and that they are in the right place to provide proper airflow.

Material and Weight

Computer tower cases are made from a few different materials, with steel and plastic being the most common. If you need portability however, you may want to look at aluminum. Aluminum cases tend to cost a bit more, but are much lighter then steel, and much more sturdy than plastic. Aluminum cases will also help to keep heat levels down inside the case, as they conduct heat much better than steel or plastic. For a home office computer, this is not that big of a consideration. For a gaming computer, especially one that needs to be portable, you may want to seriously consider aluminum, even with the cost increase.


Take all these things into consideration when looking at computer tower cases. You will find that prices are going to range from $25.00 on the cheap side (try to find wholesale computer cases online), to $300.00 for the top end cases.

Some cases will come with an included power supply. For a home office setup, this may be the most cost effective way to go. If potential noise from the case is an issue for you (particularly if you share office space), look at Antec computer cases for home office use. Antec has a series of cases with attributes like "quiet power supplies, sound-deadening side panels, and silicone grommets for the hard drives". They also provide a power efficient case with built in power supply. For a gaming computer however, the included power supply will usually not be able to power your system sufficiently. Taking airflow, layout, and weight into consideration will ensure that you purchase a computer case that will perform well for years to come, and will last through multiple upgrades.

Thanks for

"Putting the parts together was relatively straightforward. The only snag we hit (my son & I) was getting the CPU fan aligned properly. We had 3 pins in, then noticed when we turned the board over that one wasn't through.

After struggling (carefully!) for 10 minutes, we loosened the other pins, aligned all the pins and we were away again.

The hardest part, I thought, was the wiring. And here your guide really shined.

Most of the other guides ignore it, or just say 'connect all the wires properly'. So thanks for the details (because the devil really is in those wiring details)."
