Simplicity is the name of the game, and that's what you get with the Z589T mini tower from In Win. This case is designed to accept MicroATX form factor motherboards and comes with a 350W PSU already installed. The four expansion slots have locking tabs so you don't have to worry about dropping a screw.

The 2x5.25" external bays have pin locking system to easily mount your optical drives. One of the 2 external 3.5" bays also uses a pin system. That's not all that swings out. The side panel releases at the push of a button.

Underneath is a Vortex air duct that takes advantage of the large perforated area on the side panel to increase air flow to the CPU. There is a 90mm rear fan to increase overall airflow within the case.

5 out of 5 eggsSolid budget case

Pros: This case doesn't have a lot of flair, but it's easy to use, solid, and a very good budget case. I've built many systems over the years with it.

Cons: The fan/vent on the side doesn't quite match up with the CPU heatsink on most LGA775 boards. It's just an intake, though, so it's not a huge deal.

Other Thoughts: I definitely recommend this case for the beginner or expert builder.

4 out of 5 eggs

Pros: good construction and easy to assemble everything lined up

Cons: you will need to use screws for the hard drive and if you want the disk drive extra secure you can put screws in it too.

Other Thoughts: good choice for the money very quiet sturdy case

5 out of 5 eggsExcellent business case

Pros: Excellent case for a business PC - good construction and has that 'tight' solid feeling of an OEM case like many Dell's do - a great plus when you have customers that may be a little leary of purchasing a no-name brand PC. Tooless drive mounting is nice, even though I do use the screws as well.

Cons: As many have said, the 3.5" bay should also be usable for a hard drive as most of us don't put floppies in our builds anymore. Internal USB connector should start using a single plug as all motherboards use the same pin-outs for many years now.

Without being able to use the floppy bay for a hard drive, mounting two drives in the provided bay ends up with the drives mounted right on top of each other - not good when it comes to cooling. You could use the 2nd ROM bay for a hard drive (with an adapter) assuming you don't have 2 ROM drives.

Other Thoughts: I've done over 500 builds for clients using this case in the past few years and the 523 series before it. Nice clean looking design which is great for the corporate clients - most cases out there are not appropriate for the business environment - either too ugly, too flimsy or too gamey looking.

Out of those ~500 builds, I estimate maybe 30 powersupplies have failed and most have been after a power outage. The included supply seems to be more sensitive than others to off-on-off-on type power failures common when the AC fails and which surge supressors don't help any with.

5 out of 5 eggsGreat mATX case

Pros: Great quality and clean good looks. Plastic has very solid feeling to it as dose the steel panels. The tool less drive and card holders actually work and feel very secure. Included PSU is of good if not great quality. Air flow around the rear exhaust fan is nice and open, the fan itself is also quiet and seems to be of good quality.

Cons: Header for the USB ports have the ground pin separate from the voltage and data wires allowing for wiring mistakes (at worse) or simply a pain to hookup (at best). USB headers have been standardized for a long long time so this is a bit puzzeling.

Other Thoughts: I usually replace the PSU with something a bit higher quality (OEM Seasonic) so it would be nice to see these offered without the PSU for a bit of a lower price.

4 out of 5 eggsNice, but not spectacular.

Pros: Nice case for a basic PC. Works well. Everything fits tightly. Decent Power supply too.

Cons: A little flimsier and lighter than I remember Inwin being. I have a repair in here now with an older Inwin micro ATX case. It's definitely feels heavier too lift. I've built with several Inwin cases over the years. They used to have a removable hard drive sub-chassis. Now it just mounts vertically on two metal tabs that stick out in the front of the chassis. It appears Inwin has figured out how to chop cost out of their products like everyone else.

Other Thoughts: I'll check alternative brands next time to see if there's some competition for the money.

5 out of 5 eggsGreat case for the money

Pros: This is a great case for the money, small, compact, yet easily accessible and sturdy.

I like how the hard drive and and optical drives are held in, with the little tabs. Makes installation easy.

Cons: None

Other Thoughts: I broke one of the bay covers when taking it out but I think it was my fault as I wasn't patient enough. Don't force them out like I tried to.

Other than that this is a GREAT case, I will continue to use this case for my clients.

4 out of 5 eggsVery nice case for the money

Pros: Case is nice and sturdy, made from good materials. The black finish looks nice as well. The fans are nice and very quiet, perfect for a mid range home PC. Can hardly hear if the computer is on. The green tabs that hold the optical and hard drives to the case are nice.

Cons: I broke one of the 3.5" drive bay covers when trying to re-install it, I think it was my fault though. Just be careful when replacing them, don't force it like I did. They come installed, so no worries there. I put a little super-glue on the sides and set it back in there, no worries(unless you ever wanna take it out).

Other Thoughts: This is a well thought out case, I will continue to use this case for my clients, I build computers as a part of my home business. I couldn't be happier for the price.

2 out of 5 eggsI am sure if I would buy it again

Pros: Good one, but not a good place to put the hard drives.

Cons: At least with the case I got only one hard drive can be fitted without the extension bay. I am not sure where to get the extension to put more drives.

Other Thoughts: I would recommend to some one if they fixed the way hard drives can be fitted.

5 out of 5 eggsIdeal for everyday computing

Pros: Familiar design for those accustomed to this family of cases. Front USB ports are not recessed or squished or otherwise difficult to reach with a USB stick like some case designs. Tool free 5.25" and 3.5" drive mounting (like anyone puts in a floppy drive these days, but still a nice feature), side panel access, expansion card installation, and face removal. Includes 120mm rear case and power supply fans. Side air duct for direct CPU cooling. Very visually pleasing design for an office environment. Large fans run quietly, nice for office. All metal edges are very clean and rolled, you'd have to really try to cut yourself and probably wouldn't succeed. I remember the 80's when your fingers would bleed when you just looked at a case.
There's even *just* enough room beside the 3.5" bays to put the Intel or AMD sticker.

Cons: The hard drive must be mounted with screws. You can choose between a 3.5" drive bay or vertically against the rear of the face where I would normally mount a front case fan. This is an artifact of being a mini-tower instead of a mid-tower, but it would have been really nice if In-Win had put the tool-free mount on that front vertical hdd mount where it would be used instead of on a floppy disk mount where it will never be used.
Motherboard tray does not come out so it is just a hair crowded during initial assembly.

Other Thoughts: This is a very affordable and nice case for anyone that just needs a computer for daily use. Look elsewhere if you want to build that uber gaming rig.

2 out of 5 eggs

Pros: cost

Cons: System panel connector cable was TOO SHORT to reach the 20-8 pin location on the ASUS P5QL mb. Also, as others have already noted, the front panel USB cable connectors to the mb are not clearly labelled, and if hooked up randomly will probably result in burned out usb hardware - best to leave them unconnected, as no tech support seems to be available

Manufacturer Response:

We here at In Win would like to apologize for any inconvenience caused by the issue of short cable lengths included with this chassis. We are happy to mention that the problem has been addressed in the revised version of the IW-Z589T, and that a connector cable of more appropriate length has been included. We thank our users for their comments and continued support.
