Zalman Z3 ATX Mid Tower PC Cases

Zalman's Z3 range of Mid-ATX cases represent excellent value for money and boast many features you'd expect to find on a more expensive case.

Case Differences

Apart from a few small differences both of the cases are essentially identical. The main differences are that the Z3 Plus case has an acrylic side window, an extra 120mm fan (bringing the total supplied to four) and a support system for large graphics cards or extra internal fans.

Front Panel

Both models have a simple built in fan controller which can control the speed of any two of the supplied 120mm fans. With the button pressed in, the fans will run at full speed otherwise the fans will run at a slower, quieter speed.

Behind the power button are the I/O ports and they consist of a single USB 3 port, two USB 2 ports and the usual Headphone / Microphone sockets. Space is provided behind the I/O ports for devices such as mobile phones to sit while charging via USB.

Drive Bays

Both cases offer the possibility of mounting two 5.25" optical drives and four 3.5" drives. Many people also use a 2.5" SSD in their PC's these days because of their speed advantages over standard hard drives and again, both cases have the provision for one 2.5" drive.

Bottom Mounted PSU

Bottom mounted PSU's are becoming more common these days and they offer two benefits to the system. First, having the weight of the PSU at the bottom of the case rather than the top adds more stability to the system. The second benefit is that air is drawn up through the bottom of the case straight into the PSU and the warm air is then blown straight out the back of the PSU leading to lower internal temperatures. The opening for the PSU is covered with a removable dust filter to prevent dust getting sucked into the PSU from underneath the case.

Accommodates Large Graphics Cards

Large, powerful graphics cards are also catered for in the Z3 cases and a huge 360mm space is available to accommodate all but the very largest graphics cards.

VGA Support System

Large graphics card are usually quite heavy and they can sag, straining the PCI express socket they are located in because of the weight towards the end of the graphics card. Zalman have recognised this as an issue and have devised an internal support for the Z3 Plus case which if not required for a graphics card, can be used to position additional internal fans.

4* Good value case
Reviewed by Lex on 31/10/2013
An attractive case and good value (£32). Be aware that there is no power supply unit included. There are four fans, the front one with blue LED lighting. Internal cable management is adequate - just. A pity that the molex power connectors are low quality and could break easily. The internal layout is good but the tool less drive bay system is very flimsy. The side panels are slightly awkward to align when re-fixing but overall a good entry level case if you only need very occasional access for maintenance or upgrading. I would recommend this case for a low budget build.
4* Great budget case
Reviewed by John on 19/12/2013
The case is great for the price apart from some teething problems, i'll explain.
This case does come 4 fan but note that the rear fan uses a large molex so has to be powerd directly from the PSU but all other fans use 3 pin mini molex and as far as i can tell, the basic fan controller (high/low) built in the case doesnt seem to work (perhaps I'm not doing somthing right). ALso the 2 fans at the top seem to be built into the case rather than being easily accessible fan mounts. Noise is what you would expect of 4 cheap fans, acceptable and keeps the case cool, however the 5mm of foam used as the front dust filter makes a slight buzz from vibrating against the perforated casefront (putting my hand on the case where the front fan is stops this so slowing the fan down a bit would solve this).
Cable managentment is good and with some careful cable planning, even the large motherboard power can fit in the space behind.
The Side panels were a bit hard to pull out but all-in-all a good case.
