corsair obsidian 1000d
CORSAIR OBSIDIAN 1000D is a very elegant, but large PC case designed for people who need a two-computer device in one or are just fans of spacious cases and good air flow. Thanks to its construction, this case supports up to two motherboards (up to an E-ATX and a mini-ITX), two PSUs and offers a separate front panel for each of the two boards with their own Power and Reset buttons, along with USB connectors.

There is enough space for four massive radiators, up to eighteen fans (eight in front), along with five 3.5” and six 2.5” drive bays, which is enough even for the most demanding users.

Unfortunately, although OBSIDIAN 1000D is an exceptional product, its price tag is just too high when compared to the majority of other cases. For that reason, unless you are in a demand for a two-motherboard case, better skip this one and choose one that is more fit to your budget.

  • Not that great cable management

As you can see the modern market is rich in various PC cases of different sizes and with different options. So here is the guide to help you make the right choice.

All you need to know about PC cases before buying

1. ATX & ITX – what’s the difference?

Don’t panic if these abbreviations mean nothing to you. ATX, aka Advanced Technology eXtended, denotes a motherboard configuration specification or, simply put, a motherboard design. The most commonly used are Standard and Micro ATX boards. Standard ATX boards are 12×9.6 inches. As to Micro ATX, such motherboards can have the maximum size of 9.6×9.6 inches.

Another type of motherboard is Mini ITX of 6.7×6.7-inch size. Such boards are usually used in small-configured computer systems. There is also Mini ATX, which is slightly smaller than Mini ITX – 5.9×5.9 inches. One of the smallest form factors would be Nano ITX (4.7×4.7 inches) and Pico ITX (3.9×2.8 inches).

On the whole, the size of any PC case is determined by the board size it can support – usually big cases have larger motherboards and vice versa. But keep in mind that any computer case which hosts a motherboard with a bigger size can also support boards of smaller sizes.

Consequently, before selecting a computer chassis make sure what motherboard you would like to have in and then check whether a chosen PC case corresponds to your needs. If you are working on a powerful gaming machine you can find more details about suitable motherboards here.

2. Common form factors of PC cases

Obviously, all PC cases have different size and shape. Thus, there are special terms which denote these characteristics. The first one is desktop case. Such computer case has a horizontal design and is widely used in business environments in order to save the space as it can be easily placed under the monitor.

The next one is SFF, i.e. Small-Form-Factor. Well, the term speaks for itself – cases which belong to this category are more compact than desktop cases but at the same time have almost the same options. SFF cases support motherboards which are smaller than Micro ATX (usually these are mini ITX boards). They can look like shoeboxes, cubes, and book-sized cases. Thanks to such compact construction SFF cases are very popular with gaming and home theatre computers.

Some other terms which you can face while looking for a PC case include mini-tower, mid-tower and full-tower cases. Mini-tower cases are under about 14-16 in high, what coincides with the size of desktop cases. They usually have only one or two external bays and support micro ATX boards.

Mid-towers are about 17-21 in high and have from two to four external bays. And if mini-towers can host only one GPU, this type of cases can support up to two. Recently there has also appeared a new term – midi-tower, which presupposes a case smaller than mid-tower but larger than mini-tower. Midi-towers are with two to three external bays. Still, this term is quite interchangeable with mid-tower.

As to the full-tower cases, they have a height from 22 to 27 in. Full-towers usually have from five to ten externally accessible drive bays and are supposed to stand on the floor. They support ATX, EATX or even XL-ATX motherboards. All towers which have more than 27 inches in height are called super or ultra towers.

We also can’t but mention MOD-tower. This is a case system which can be modified by putting new cases on its top in order, for example, to add more cooling capacity.

Nevertheless, we have to underline the fact that different manufacturers provide different definitions for their case forms. It’s all up to provider how to call its PC case models. Thus, always clarify the accurate size of computer case you want to purchase.

3. Drive bays

Driving bays can be of different size – 5.25-inch, 3.5-inch and 2.5-inch.The biggest one, i.e. of 5.25-inch format, is used with an optical drive. This can be either a DVD burner or a Blu-ray drive. Such bays are widely used for hosting of front-panel devices, e.g. temperature readouts or fan controllers. They can be also applied during the installation of additional panels for extra ports on PC front side. Such 5.25-inch bays are used in SFF or mini-tower cases.

The second type of drive bays is used for the installation of platter-style hard drives. Some of the tower cases have 3.5-inch bays. As to the 2.5-inch bays, they can be easily implemented even in the tiniest parts of the case thanks to their compact size.

4. Cutaway for CPU cooler

Obviously, your new PC case will host a cooler. Therefore, one of your tasks is to check how well a chosen computer case is adjusted for a CPU cooler you plan on buying. Note that most of the top-notch CPU coolers need a backing plate or other mounting hardware which is installed from the board underneath.

5. I/O shield

This part of PC is placed on the back of computer case. It has special cutouts for different ports of the board and serves as a protection of the motherboard while inserting cables to the pre-cited ports.

But bear in mind, that I/O shield comes together with a motherboard but not a case itself. Consequently, I/O shields aren’t interchangeable between different boards but they can be used for different PC cases because they have almost the same standard dimensions – 1.75×6.5 inches.

6. Motherboard tray and standoffs

First of all, let’s clarify what motherboard tray is. In fact, it’s just a place where a board is located. A motherboard tray is placed at the bottom of a computer case and has special holes for the motherboard standoffs. By the by, if earlier most of the trays were removable nowadays it’s quite an uncommon thing.

As to motherboard standoffs, these are small brass-looking spacers that you can find between a board and a case. Standoffs are screwed into the PC case and have a motherboard fixed to them. Note that they help to prevent an electrical short as they raise the board above the case and as a result, the soldered parts don’t contact it.

You can usually find these brass bits in a small bag which comes together with a PC case. Their installation is not complicated because there are special marks near the holes in the tray, which will help you to find a necessary hole for this or that standoff.

7. What is PSU?

PSU (Power Supply Unit) serves to traffic electricity to such computer components as motherboard, drives and fans. PSU looks like a big box and it’s typically placed either at the top or at the bottom of PC case. It is mounted by means of screws through the backside of the computer case with a special big-sized cutaway, which also plays a part in the ventilation process.

Today most of the tower cases support ATX (i.e. full-sized) power supplies. Those PC chassis which belong to the category of compact SFF cases have PSU of SFX form factor, in other words, those of a smaller size.

PSU is one of the most important things for building powerful computers. But if you belong to the category of avid gamers then this element should be number one on your list as your PC will need more power than an average one. Here are some of the best power supply units for gaming.

8. Fan mounts

Fan mounts are surfaces inside a computer case, which are used for the installation of additional ventilation in your PC. They can be of different size – 80 mm, 92 mm, 120 mm, 140 mm and 200 mm. Still, 120-mm and 140-mm fan mounts are the most popular.

Some of PC cases have also got removable air filters, which cover the front face of the fan mounts. Such a filter would be a great additional supplement to your PC case as it reduces the amount of dust inside a computer chassis.

9. GPU clearance

This term denotes a space your GPU (Graphics Processing Unit) needs to fit in your PC case. As many modern PC cases have removable parts GPU clearance can vary. For example, if hard drive trays in your computer case can be removed it means that the space required for a video card can be also extended.

Usually, if a GPU clearance has more than 12 inches then it will be able to support almost any video card. Still, be especially attentive with very long cards. The point is that their power connectors, which extend from the trailing edge, can require some extra space in your PC case.

10. Drive sleds and drive stealthing

Drive sleds are usually made of metal or plastic and look like frames which slide in/out of a drive bay. They are used mostly with 3.5-inch bays but can also cooperate with bays of 2.5-inch size. Some PC cases have drive sleds which allow the drive to contact a backplane system with SATA data and built-in power connectors. In this case, the drives are hot-swappable.

Some of today’s computer cases have also got drive stealthing which presupposes an optical drive hidden behind a door or panel in order to bring a smooth look to the PC-case front side.

Drive stealthing can be achieved in different ways. It can be done by means of drive-bay cover with a flip-down door, which allows the drive tray to pop out. The other option is more popular with PC cases of premium class. In such cases, there is a special slot for the optical drive where you just put a disc. This is achieved via a slot-loading and trayless optical drive mechanism.

11. Types of optical drive

Some high-grade PC cases can also require special types of optical drive – slim optical drive or slot-load optical drive. A slim optical drive is much smaller and more fragile than a typical 5.25-inch bay device. This optical drive is mostly used in laptops with SFF form factor. Slot-load optical drive is used in PC cases with drive stealthing, so it goes with a tray for a slot-feed mechanism.

12. PC case ports

Ports which are a part of computer case are usually called Front I/O. They can be placed on the front face, on the top front of PC case or down one of its sides. These ports can include headphone and mic jacks, USB 3.0 and 2.0 ports.

Your task is to make sure that your PC motherboard has all matching headers for ports of a new computer case. If it doesn’t then you’ll need to buy adapters or expansion cards in order to involve ports into the working process.

By the by, speaking of the headphone and microphone jack it should be mentioned that older and newer PC case models can have different connectors. Most of the computer chassis have a cable with a 10-pin header connector, which can be plugged into a pin-grid on the motherboard. It is also called “HD Audio” header. The older versions of PC cases usually have a forked cable provided with connectors for HD Audio and AC ’97 headers.

Some of the computer cases can also have two or four ports on the back of the case, which enable you to install water-cooling hardware inside the chassis. These ports stand usually in a line with silicone rim or a rubber. Such ports are called hose passthroughs.

13. Expansion slots

One more characteristic you should be aware of is the number of expansion slots supported by the PC case. Expansion slots are special spaces which can be found in the back of the case and are often covered by the metal strips, which can be removed. The number of such slots in the PC case can vary. But usually when the form factor of a case matches the size of the motherboard then you won’t have any troubles.

14. Thumbscrews and cables

Thumbscrews are used in order to keep together side panels of PC case and its inner hardware. The point is that thumbscrews may not require any screwdriver to add or remove different parts of a computer case. Still, very often it may not work and you’ll need to take a screwdriver for such changes.

Cable management denotes the number of special features a PC case possesses, which help to improve the airflow and make the interior look cleaner. It includes the number of cutaways, some extra space behind the board tray, quality of cable cutouts (whether they are lined with soft material in order to minimize the wire chafing or not) etc.

That’s it. Now you have enough knowledge to pick the PC case of your dreams.
