5 out of 5 eggsOutstanding hotswap case

Pros: -Compact
-Hot swap!!!

Cons: Wasn't free...

Other Thoughts: I use this case as a wiping station for hard drives. It works perfectly since this is a hot swap case and you do not have to run cables to each hard drive. Plug in, wipe, and your done. I'm using a Lexar ZX micro USB to house multiple bootable ISO files including DBAN.

5 out of 5 eggsPlain, well-thought-out case

Pros: Lots of drive bays in a small package -- perfect for a fileserver (which is what I built). 5 hotplug bays plus 3 more spots on a removable base plate, and everything fits together nicely.

Cons: The opening for the power supply is tight -- I had to peel the decals off the power supply to get it to fit. There's not a lot of room for unused power cables, and if you don't secure stuff carefully, stray cables will jam the fans.

3 out of 5 eggsOk NAS case but lacks quality

Pros: 5 Hot Swap Bays
Toolless Design

Cons: Runs warm
Fans are somewhat loud with filter QA issues
Cramped Cable Management
No Front USB
Bright LED Power Button

Other Thoughts: Using this case as a dedicated NAS server with a ASRock E3C226D2I Intel G3220 Kingston 4GB ECC RAM Corsair CX430 PSU and 2X WD Red 3TB 1X Seagate Barracude 3TB 30GB SSD(OS) plenty of room for expansion.
From first startup this case gave me problems the front 140mm fan filter was not properly finished with burrs around the edges and the fan hit these each revolution making a loud racket. I removed the filter altogether and used tape to create the vacuum in the front. The back top fan made a very low pitch clicking noise at full RPM, I contact Lian Li over 2 weeks ago without hearing back from them. Consider ordering a couple Fractal or Scythe fans if you plan to sleep in the same room with this. Hard drives run about about 6-8C warmer than a Antec 900 case being in the same room. The PSU slot needs a centimeter more clearance to fit PSUs better only after removing the stickers off a Corsair CX PSU was I able to push it in. The powerbutton LED is blinding at night dont bother connecting the LED power cables.
If you want a ITX form factor look at the Fractal Design Node 304 .
For the $100 Lian-Li is asking I am disappointed not just the fans but how thin the paint is on this thing my Antec seems to be holding up way better and its over 4 years old. The fact Lian-Li has not even returned my messages in 2 weeks shows they dont care about their customers. I picked this case up for $55 with rebate otherwise this would have been returned to Newegg ASAP.

5 out of 5 eggsGreat case for my FreeNAS build

Pros: - 5 hot pluggable bays
- This version supports both molex and SATA power connectors.
Thumb screw plate for PSU which helps on initial install and troubleshooting later on.
- Small footprint.
- Can take the sides off very easy without tools.

Cons: - A little harder to work on with the ATX PSU on top of it all.
- Pay attention to the mobo stand-off when you take it out so you put it back right. The bottom goes inside the case frame and the top outside of it. I could see doing this twice if you put the bottom on the outside.

Other Thoughts: One of the reviewers mentioned to get left angle SATA cables. If you do that, they will angle upward, not down. You are better off with two longer right angle ones for the top two bays, then 3 or more right angle slightly shorter ones as you move down the drive housing and get closer to the motherboard.

If anyone cares about this kind of thing the powerLED is blue.

5 out of 5 eggsPerfect case for SOHO NAS

Pros: I got this to replace an aging Drobo, and move to something with some better reliability. I decided to build my own NAS out of cost and performance considerations. (Went with unRAID as my OS. Not the most advanced, but it does a good job and is easily recoverable in the event of data loss.)

The case itself is PERFECT for a NAS. No 5.25" bay, 5 hot swap 3.5 bays, and more mounting area on the floor of the case. I currently have 5*2tb drives in the main bays, and a 256gb drive on the bottom for cache. I'm booting off a USB stick, so that I can keep the case dedicated to storage.

I was a little apprehensive of the aluminium construction, as I've only ever really used steel, but Lian Li has made an astonishingly strudy case. I'm very impressed with the build quality.

It is a small case, and with the PSU in, it's impossible to get to the motherboard. However, as cramped as it is, the airflow makes perfect sense. There's an intake on the front, exhaust on the top, another intake vent on the bottom, and the PSU will also act as an exhaust for the CPU.

Cons: Noise. Stick this thing in a closet or replace the fans. I have it sitting in my wiring closet, but I can hear it when I'm in there. If you're going to sit it somewhere that's out in the open, change the fans to some Fractals or something quiet.

Fingerprints. It is a total fingerprint magnet. While it's not a real issue, it's just a minor annoyance.

Other Thoughts: SATA connectors are now situated horizontally unlike previous versions that required "left-angle" SATA connectors to prevent an unhealthy bend radius. I will absolutely recommend you get 5 angled SATA connectors, and go ahead and wire up all bays regardless of if you are using them initially or not.

5 out of 5 eggsPerfect home NAS case

Pros: Case is well designed. Makes very efficient use of limited space. Lockable Hotswap bays are cleverly designed, convenient and plentiful, plus the bility to mount additional drives at the base of the case. Designed to be able to accomodate video cards if needed. Also capable of taking standard ATX power supplies. This was the perfect case for my home NAS project.

Cons: No surprises, space is very limited, especially once you get the power supply in there. You'll have to make sure to install the power supply last and be meticulous about your cable management, especially if you also plan to fit a video card inside. Speaking of video cards, if one is mounted you may not be able to mount full-size hard drives at the base of the case, (only SSDs or similar) but that's what the hotswap bays are for. The cutout for the power supply is so tight that it would have scraped the labels/decals off on my power supply if I slid it through - which it seems like it was designed to do as the power supply completely blocks the motherboard once installed, and the ability to slide it out of the way is perfect for when you need to work on it. This is all stuff to be aware of, but nothing worth taking an egg off, this case is designed to fit a lot in a small package, so this is all to be expected.

Other Thoughts: As a person who builds server for a living, I was pleased with the design of this case. Lian Li managed to strike a great balance between it's simple, pleasing design and functionality with excellent usage of space and intellegent airflow. The case draws air in from the sides of the case in front, moves it across hotswap drives, motherboard and PSU and exhausts out the top in the back. I don't think I'd ever use this for a workstation but it's pretty much perfect for a NAS/fileserver which is what I'm using it for. When I saw the room for expansion card I thought less video card and more RAID card or SATA card. I got by fine with a standard PSU, but a modular power supply would be very beneficial here. Hotswap backplane has both molex and SATA power connectors and by the looks of it either can be used. They are so close together that both connectors couldn't be connected at once anyway. I went with SATA power and the drives spun up just fine.

5 out of 5 eggsNAS Case

Pros: Excellent case - I was shaking my head with disbelief at how well this case is made. All the usual trimmings of Lian Li - well thought out - I have this thing packed out with 6x 3Tb drives and 2x 120Gb SSD's running NAS4free on a supermicro X7SPE-HF-D525 - headless with IPMI and the web interface on NAS4free - it is in the corner of our basement just purring away providing "limitless" backup and storage space

Cons: Cable management - it is a rats nest in there with 6-3.5" drives and 2-2.5" drives plus all the power supply cables. I didn't have any issue with PSU mounting - but I can see that with a longer PSU it would be a problem - My PSU has just an 80mm fan at the back - not the bigger 120 on the bottom

Other Thoughts: Highly recommend if you want to pack a quantity of drives and have a solid case

5 out of 5 eggsGreat Little case

Pros: One of the biggest pros is that you can now use right angle sata cables. Sorry newegg but you won't let me upload a picture to show the big change. Please change some of the pictures for the case. Sata cables more than 12" are not needed except in extreme cases. The sides pop off and the fans are easy to get to for cleaning.

Cons: I wish it had Dual LED Power Switch like the Lian Li PC-Q28. That would have made this case complete. Lian Li if you are listening - Please make available the above mentioned power switch.

Other Thoughts: I love the fact that the fans are easy to get to, and that it will be easier to clean out the case as needed for dust (I have a lot of it.) I will be buying another one of these cases to house a small server in. I figure 4TB X 6 will be enough storage. Now to order the 10 and 12" sata cables. The 18" cables are way to long.

4 out of 5 eggsLian Li Mini-ITX Case

Pros: -Plenty of bays
-Easy to take off/put on side panels
-Rubber grips for HDD bays to reduce vibration.
-Great quality case overall

Cons: -Cable Management? No room for it especially when you want to have a video card in the case. You might be able to get away with a 650 Ti with 6 HDDs and 1 SDD.
-Stock fans are pretty loud and airflow rather poor so I had to replace them to improve the temps and airflow in the case.
-Can't remove the top of the case; made it hard to install 24 pin and 4 pin on mobo since the PSU is directly on top of the mobo.

Other Thoughts: Before I replaced the case fans, the temps averaged about 60-65C. When I replaced the case fans and undervolted my APU; that got the temps to go below 45C. That's with 6 HDDs and 1 SSD.

On another note, installation of interior components took a lot of planning/redoing and I even broke a cable holder that's built into my PSU because there wasn't enough space for it.

I was thinking that this case could've used some front or top USB ports to make use of the mobo's front panel USB header. Oh well.

4 out of 5 eggsSo many improvements yet still lacking in power supply length

Pros: Let me start by saying I absolutely love this case, the finish, the quality, the simplicity, I LOVE the ability to put a full size card such as an Nvidia GTX 780ti or now trumped Titan in this mini powerhouse. They've come a long ways from the PC-Q07's with the 6 tiny laptop size screws to remove one side now it simply pops-off. I love it! I love the pseudo hot swap bays (can be made true hot swap with appropriate RAID card) one power plug per two hdd makes cabling easier and simpler.

-Simple HDD cableless design once it's installed it's a snap to pull a drive.

-Simple hdd bay lock for all drives with one thumb screw

-Easy tool-less design case doors pop off without so much as even a thumb screw, thumb screws to remove bottom hdd tray

-Quality rubber feet absorbs noise and looks classy

-Beautiful quality finish, even down to normally sharp internal edges

-Quiet design for standard mechanical hard drives with simple slide in design with rubber boots on the screws

-airflow is actually quite good if you use a small power supply top exhaust fan is quiet and moves adequate air though I'd remove the screen that seems to be filtering air before it exits (I assume this was for design purposes as it darkens the holes to look more black rather than an empty window looking into the case)

-Large 140mm intake fan keeps HDD very cool

-Intake screen to stop dust bunnies in their tracks on the underside of the case which is easy to remove and clean or take off to improve airflow

Cons: MAKE SURE YOU REALIZE THERE IS NO OPTICAL BAY FOR CD-ROM ETC. (use a usb drive to install windows etc)

In my opinion this case has an identity crisis, with the ability of so much storage for a home server (of which I highly suggest this case for) amongst the ability of a full size graphics card. Long(er) PSU's that you'd need to handle a graphics card such as a GTX 760 or 770 (or more amp hungry) are too long for this case. The power supply setup they've been using for so long needs a redesign, or possibly making the hard drive bay removable, or changing the orientation of the HDD.

The vent on the bottom is great though I would either move it more towards the front or make the vent longer towards the front so that GPU intake fans will better utilize the fresh cool air. In a case such as this you want a centrifugal fan design on the video card, to intake air from the bottom of the case out the back, rather than turning this case semi-nuclear with a circulating fan.

Again I would've preferred either using another mount point for a couple SSD's over having a 5 full size HDD rack occupying the space you'd need to make this a true LAN Party "Hero"case. they had room to put a slim mount for optical above the fan, and gone with SSD's as they give plenty of room for full size PSU's I would have called it perfection.

Other Thoughts: Intel Pentium G3220 LGA1150 3.0GHZ (for lower case temps)
Crucial Ballistix 8GB DDR3 1600MHZ CL8 x2 (low profile is important here)
Samsung 840 256GB Pro x2 RAID0
PC Power and cooling Silencer 610 (49 Amp 12 volt rail)
EVGA GTX 770 OC edition

I was worried the "weak" 3220 would be a big bottleneck
Quick comparo:
Core 2 Quad Q6600 2.4GHZ was getting 125fps in Diablo 3

3220 @ 3.0GHZ is now 244 fps in D3

Same drivers same windows load swapped drive over after reinstalling drivers to test with same default settings and same settings in diablo 3 I was getting over 300 fps menus settling to 244 fps in actual town in game.

I've built hundreds of computers in cases such as Thermaltake, Corsair, Antec, Coolermaster, Silverstone, among many more generic brands. I've come to respect Lian LI in the basic aspect of quality and simplicity. I have one of the giant red PC-V1020R (my favorite when size is not incorporated)

BONUS: I would like to inform those that made it this far through my rambling that there is actually an extension piece to allow longer psu's to mount (albeit protruding out the back an inch or so) it can mount a true full size PSU. As Newegg no longer stocks it you will need to Google PE-01 (PE-01B is the actual for the black model) then there WILL be cake. thx for reading and thumbs up so people can know more about this case!
