The BK623 from In Win is designed for your digital lifestyle. This MicroATX media center case gives you plenty of room for customization, and still fits well with the rest of your home theater equipment. The case is taller than many, so it can accept full height cards, which increases your expansion options. This means you can use today's advanced video cards so your high definition video content will look its absolute best.

Cooling is of prime importance, and the BK623 has taken that into consideration. They've also considered that you’re going to be using this case with a home theater setup, so you don't want a noisy system. The removable optical drive cage is part of a thermal isolation system that keeps the CPU and the rest of the system separated. This creates more efficient cooling zones without the need for extra fans and keeps the system a few degrees cooler and quieter than a regular system.

  • newegg Tower or Desktop Convertible The In Win BK623.GLS300BL can be oriented horizontally or vertically to function as a tower or desktop chassis for the ultimate flexibility.
  • newegg Partition Plate Cooling Technology By separating the CPU fan from the heatsink to reduce back draft, In Win’s innovative partition plate cooling technology (PPCT) efficiently guides the airflow in a unilateral direction for enhanced thermal performance.
  • newegg Built-in 300W PSU The In Win BK623.GLS300BL is equipped with a 300W power supply unit to handle typical power consumption for most MicroATX systems.
  • newegg Convenient Front I/O Panel The In Win BK623.GLS300BL features a convenient front I/O panel for easy access to four USB 2.0 and two audio ports.

4 out of 5 eggsGreat case, a little cramped

Pros: MicroATX case for my HTPC that fits in my media center
Has space for 2 HDDs and a full-size optical drive
Near silent with stock Intel cooler
Comes with a power supply

Cons: Wiring is very tight. The power cable for the CPU is simply too short for my GIGABYTE GA-H81M-HD3 motherboard and goes across the expansion card slots. Thankfully, I'm not using them.

The power LED is way too bright. I had to put a piece of electrical tape over the LED it was so bad.

Getting the case opened and closed could be easier. It was especially difficult to close it properly after getting everything installed.

Other Thoughts: There is a rubber slot to run the cables for the optical drive through the black piece that fits over the CPU fan.

There are two power connectors for drives. One is designed for the optical drive and the other for the HDD. Unfortunately, both cables have one SATA and one molex power attachment. If you want to run 2 HDDs like I did, you'll need a molex to SATA adapter. Repeat, IF YOU WANT TO USE 2 HDDS, YOU'LL NEED A MOLEX TO SATA ADAPTER. I guess this case could be used with older systems that still use PATA.

5 out of 5 eggsTiny yet fits full-height PCIe video cards

Pros: Exterior dimensions are very compact (less than 6" wide)
Power supply driven within 80% of 300 W without issues

Cons: Small case means there's almost no room to work when swapping parts
No auxiliary PCIe power connector (efficient power video cards only, i.e. Radeon 7750 @ 45 Watts)

Other Thoughts: I use this case "upside down", with the power supply at the top drawing cool air in. I have a flat rabbit cage fan (originally intended to be a PCI slot cooler) exhausting warm air from the top of the case. Video card is a "silent" model, huge heatsink does actually fit into the case. Large aftermarket CPU coolers will probably fit only if the optical drive is removed.

5 out of 5 eggsIndustrial art

Pros: After hundredss of times upgrading the insides of this case, it still comes apart without falling apart and goes back together right every time
At first, I thought it was flimsy. It isn't.
Top-grade engineering.
Perfect size for me.
Runs cool and silent with just the CPU fan and the PSU fan, since I learned to properly use the partition plate.

Cons: It ate CPU coolers until I started sealing the air holes on the partition plate with duct tape.

I learned from burning out a CPU cooler's fan that extra care is needed to make sure the cables to the DVD burner stay out of the fan. Duh.

The stick-on feet really suck, but I got some aftermarket feet that work great.

Other Thoughts: After I learn to administrate a Smoothwall firewall I built from spare parts, I'm buying another of these cases for an Ubuntu Server/WordPress/Moodle webserver that fits my standup desk.
A $7.00 Arctic Cooling Alpine GT 64 has kept my AMD A8-5500 happy for 6 months or so now.
It just got an ASRock FM2A88M motherboard and I'm way happy with the way the machine works now.
This is a helluva long way from the Sinclair ZX80 I started out with in 1979.

5 out of 5 eggsInWin SFF Tiny Tower

Pros: -Perfect Form Factor
-Fits full size Graphics
-300W Built-in PSU provides plenty of power for a variety of configurations
-Cooling partition works perfectly for stock Intel coolers
-fits 2 x3.5 HDD's, and a 5.25 CD/DVD/BD Drive
-Lights on the front of the case and case itself are attractive.
-Made from Solid Materials
-Device is less likely to tip over than thin models due to full width

Cons: -Ventilation is not in excess
-working with just one unit might be confusing due to lack of instructions
-Top of the case can be difficult to get on

Other Thoughts: Used in 20+ Workstation configurations for the ease of assembly and small form factor associated with the device. These units do not seem to collect as much dust as the dell units that they replaced. Employees love that they have a much greater amount of leg room.

It takes me approximately 40 minutes to complete a build in this case with having to unbox everything as I go. This is pretty quick and allows me to produce more units in less time.

5 out of 5 eggsGreat case for a trunk mounted CarPC

Pros: This is a very small footprint case, just what I need for a trunk mounted CarPC. My 2011 Sonata didn't have room under the front seats for my old Travla c289 case, so I had to go to the trunk. This case fits nicely in the right back corner behind the tire. It allows for an external 5.25" and 3.5" drive bay, one for an SSD boot drive and one for a 3tb data drive. Being able to easily remove drives allows me to make updates away from the car. Did I mention how small this case is?

Cons: Air circulation isn't the best, so you really need to plan ahead and use low power and low heat output components. Also, beware that a long drive in the 5.25" external bay will sit over part of the CPU, so you will need to stick with the stock heatsink / fan or go with a low profile model with no more than 70mm combined height.

Other Thoughts: My situation is a little extreme in that I needed something small but also something with good air circulation. My trunk mounted PC is for a car in the Atlanta, GA area, so it gets to some pretty extreme temps in the trunk. I cut an additional 2 holes in the side to mount an 80mm and 92mm fans (Noctua). That helped take temps on my Intel 2120t to 50C under heavy load. So the extra fans reduced my temps about 15C and really wasn't much louder, got to hand it to Noctua. This is with an ambient temp around 30C in the trunk. Best yet, I have more room in my trunk for strollers and other baby necessities.

5 out of 5 eggsstands up well

Pros: solid, well made case with a quiet fan. Smallest one I could find that can take two hard disk drives; I put a RAID controller in it and it worked like a charm. Have had it for 2 years with no problems.

Cons: because it is a small case, everything is a bit tight.

5 out of 5 eggsGreat mATX Small Form Case

Pros: Awesome little case for basic PC configurations. Took me a bit to figure it all out, but after that everything came together nicely. I like this case so much I just bought 3 more for various projects.

Cons: Instructions aren't the greatest, but didn't take long to figure out how it all goes together. Not necessarily a con, but not sure how this case would do with an add-on video card.

Other Thoughts: I got this case for my wife's Windows 8 Pro system. She has a small desk in the kitchen so space is at a premium. This case was just what was needed. Much smaller than her old mATX case. I love the design, unique and functional. I'm building three more systems (a couple test units and an HTPC). Great job InWin.

4 out of 5 eggspretty good case

Pros: This seems like a pretty well designed case. It's fairly inexpensive, it isn't ugly, and it has a good-enough-for-most-purposes power supply with a very quiet fan. I don't have any complains about build quality.

Cons: The optical drive bay is placed such that, depending on motherboard and CPU, it may partially block the CPU fan. The power supply does not have the 8-pin atx 12v power connector needed by some newer motherboards. (I've been using a molex-to-8-pin adapter and haven't had any trouble.) The cover can be tricky to get on.

Other Thoughts: I have two of these, one housing an atom-based system, and another with an amd A10. For the atom, it works great, you can't even tell the computer is on. For the A10, I probably should have opted for a bigger case for the sake of airflow, but everything did fit.

5 out of 5 eggsGreat case

Pros: Small size, intelligent layout, aesthetically pleasing exterior.

Cons: No case fan other than the Intel CPU fan, not much room for a stand-alone video card.

Other Thoughts: This case is one of the best thought out matx designs around. Very small size accommodates three 2.5" hard drives and a regular size CD-DVD drive. No room for a discreet video card, but not necessary given the newer CPU/GPU combo processors. I was able to do an extremely clean installation in this case. Also, the case is very pleasing to the eye. Good job INWIN!

4 out of 5 eggsSweet Little Case

Pros: This is my second one; both used for non-gaming home computers. Sits under my computer table on 11-inch wooden stool - very quiet and easy to reach. Well-built and relatively easy to work with, but don't try to stuff too much inside. I really like the small size, solid feel, and quiet operation. Got a new 23.6-inch back-lit Asus LCD display for a very nice home computer system.

Cons: Thermal partition plate does not quite fit over ASRock H77-Pro4M motherboard, core i3-2105 CPU and stock cooler. I tried reversing the moveable part, but still about a quarter inch too tight. Reassembled without the thermal partition plate, but added a slot fan and fan speed control in back for air flow. CPU temperatures usually in low 30's in normal usage, getting closer to 50 with significant video processing. This arrangement does exhaust perceptible amount of air from the case via the slot cooler.

Can't seem to get the front headphone jacks to work. I have not chased this further, since I don't use headphones anyway.

Unlike the same model case from several years ago, the current case does not have a toggle switch on the power supply. Also the power supply fan in the new case does not seem to exhaust as much air as the version from several years ago.

Other Thoughts: Core i3-2105 (with HD3000 graphics) with stock cooler
ASRock H77 Pro4 M Motherboard
8 GB Crucial DDR3-1333 RAM
500 GB WD Caviar Blue Hard Drive
Asus DVD Burner
Evercool SB-F1 PCI Slot Case Cooler
Apevia FC-01 Multi-Fan Speed Controller
Windows 7 Home Premium

The result is a responsive little computer. Not much space left inside the case after connecting all the cables, but the thermal performance seems satisfactory and the system is quiet.
