5 out of 5 eggsBest Home Server Case Ever

Pros: Can hold a ton of hard drives in a small case. Depending on your configuration, you could have four 3.5 inch hard drives in the hard drive bay and another one in the 5.25 inch bay (Actually has holes to install a 2.5 or 3.5 inch hard drive natively) and another one on the bottom tray mount along with two 2.5 inch hard drives next to that one for a total of 8 hard drives!

Features rubber isolating mounts for all of the hard drive mounting locations which dramatically reduces vibration which helps your hard drives last longer.

Great ventilation via a front and top 140 mm fan mount with included fans. Also has an optional third 140 mm fan mount at the bottom of the case, but the bottom hard drive mount tray has to be removed in order to use it. Either way it provides some ventilation from the bottom of the case through a removable dust filter. The front fan also has a dust filter attached to it. Both fans connect via a 3 pin fan header but also come with a 3 pin to Molex connection if you don’t want to use the 3 pin connection.

Unified Hard Drive activity and Power Light LED as the power button lights up blue when on but when the hard drive is working it flashes a purple color and then once it stops its back to solid blue.

Separate motherboard tray which my old Lian Li case did not have, the board attached directly to the back side panel so it could never be removed without taking the board out first. Also the separate tray has a cut out for accessing the back of the CPU socket to make CPU cooler upgrades easier and quicker.

USB 3.0 connectors in the front and connects via the USB 3.0 internal connector (Not what is shown in Newegg’s pictures) not like the connection my old Lian Li case had which was standard USB 3.0 cables that had to run outside the case to the USB 3.0 connectors on the back of the motherboard. Also includes a convertor to convert that connection to a USB 2.0 motherboard header connection in case you don’t have a USB 3.0 motherboard header.

Very easy and tool less design from the hard drive mounts to the side panels. These side panels are much improved from the previous design on my old case which had 8 tiny screws just to take off one side panel unlike this design which just pops off very easily and quickly.

The front panel connector wires are black! Not in a bunch of ugly colors like the one pictured on Newegg.

Has some room for cable management behind the hard drive hot swap bay, it isn’t easy but it’s there.

Holds a standard size ATX power supply (Careful on length though as others have stated the wires may not want to make the turn due to the hard drive bay)

Painted black inside the case

Cons: It would have been nice if they had made ventilation holes on the left side panel so that my power supply could be flipped the other way and take in fresh air from outside the case rather than from inside facing the CPU cooler.

The included fans are very weak and don’t move a lot of air even at full speed which is disappointing. Most likely they were aiming for silence but either way I can change them out at least if I want or need to.

Front microphone and headphone jacks look ancient and cheap and don’t match the high quality look of the rest of the case.

Unnecessarily long front panel audio connector cable considering the case is tiny. The one case where I don’t need it to be long it’s the longest one I’ve ever seen.

Other Thoughts: Overall this is the best little case I’ve ever bought for a small home server. It has great ventilation and holds a bunch of hard drives while still maintaining a small form factor unlike every other case I’ve looked into. It does come at a premium price but for everything I could stuff in such a small space it was well worth the investment.

Power supply: SeaSonic SSR-360GP (This power supply fits fine)
My old case was a LIAN LI PC-Q11B

5 out of 5 eggsLove the fit and finish on this case!

Pros: Very nicely crafted, sturdy and easy to work with. Rubber grommets for the front fan and all hard drive mounts. Nice large and quiet fans to keep the air flowing, with filters for the occasional cleaning.
Bonus, I must have the newest revision with a USB3 header for the motherboard, and an adapter to use the USB2 header internally if you don't have USB3. No external cables, woohoo!

Cons: Front fan was loose from its mount, but nothing damaged. Rubber grommets already installed and fan slid back into its mounting grooves without issue.

Other Thoughts: This is the start of my new home theater and/or main workstation rig, so I understand the challenges that await getting everything just perfect. I have a carefully crafted parts list, so it might be a little while until complete, but maybe prices will drop!

1 out of 5 eggsBait and Switch :(

Pros: The case seems like a pretty good case. Did my research, liked the color, thought it would be nice. Purchased it when it went on sale.

Cons: This is one of my first bad Newegg experiences. I ordered the black one, got the silver one. No way was I going to be able to make the silver version of this case work with my mostly black media center system. Call them up to get them to switch it to the right one and they have me send the silver case back in. Afterwards, I get a notice I was getting a refund because the item was out of stock. A week after I send it back, the site shows the item back in stock. Makes for an unhappy customer. It looks like they just didn't want to offer it at the sale price. Now if I want to buy it, it will cost me 50 dollars more.

Other Thoughts: I wish they would have just said they were out of stock and not get me baited and switched out for the silver one. The time I wasted getting it RMA-ed was quite frustrating.

5 out of 5 eggsWow...

Pros: First time investing in a Lian-Li case, and probably not my last. I generally purchase cheaper plastic cases, but wanted something that did a better job of dampening HDD vibration for a home NAS. Lian-Li really took everything into consideration with this case -- rubber grommets for drive mounts, completely tool-less, light aluminum chassis (without sharp finger-slicing edges!), etc. When pushing against the case with both fingers, there's virtually no vibration (a minor, minor amount, but it might even be from fans or other components...).

Cons: The only thing that I was a little bummed about was the USB 3.0 front handle headers. They're not actual motherboard headers, but rather male connectors that are designed to be run to the back of the case and plugged into the motherboard's back panel. I already knew about this from external reviews, however, so it's not really a gripe, just a wish!

3 out of 5 eggshigh quality, great look, versatile, not the easiest build

Pros: There's no denying the quality of the materials used in this case. From the tool-less/screw-less side panels, the HDD trays, to the chassis feet Lian Li did not cheap out on this.

There are multiple mounting options for storage including hot-swap rails and a removable floor-mounted drive tray. Plenty of rubber bushings and screws are included to mount several 2.5" and 3.5" drives.

You could choose to forego the floor tray and mount a 140mm fan (not included) as well.

Cons: My biggest gripe is with mounting a standard ATX power supply. In my case the mounting hole on the back of the case can barely receive the PSU. Even though you have to mount a plate to the PSU which covers the opening completely, the opening is so tight that the PSU has to be forced in. I had to return a PSU I ordered that had a small LED because the LED wouldn't clear and in fact I had to scrape the stickers off of the replacement PSU to get it to fit. If you're handy you could use a dremel or a file to give yourself some room, but I feel this shouldn't be necessary on such a premium case.

PSU issue aside, this case is tight. If you're building a mini-ITX you probably have an idea what you're getting into but considering the overall size of the case I thought there would be more room inside to work with. The drive racks below the ODD are permanently mounted although it would be very useful to be able to remove at least the bottom 2. I ended up stuffing wiring inside one of the empty rack bays.

Price (I paid $140). You could piece together an entire ITX build for around the price of this case.

Other Thoughts: I'm using this in a HTPC/Steam setup. Noise is not an issue and I'm still tweaking some things but so far, so good.

5 out of 5 eggsNice case

Pros: Nice case with a user friendly design. Installing drives is easy and tool less. Removing the side panels involves just pulling them out. I can't comment on the fans since I replaced the stock fans with 2 Noctua's. I've got 5 drives installed in mine and had zero issues getting them in. Overall I'm happy with my purchase.

Cons: If you have a standard ATX power supply it goes without saying that those cables make for a tight fit. Also getting the IO shield in was a royal pain.

Other Thoughts: I didn't buy an optical drive because for my needs I didn't need it. I used the space to stuff power supply cables into.

4 out of 5 eggsSmall form factor powerhouse

Pros: Nice compact design. It's small but can handle a lot of drives. My setup has four hard drives, DVD-ROM and an SSD. The air flow is good and the fans are very quiet.

Cons: You are limited to using 5.5 inch power supplies. I couldn't find a modular power supply that fits so I had to use a non-modular model. Needless to say, I had unused cables that needed to be tucked away in little space remaining.

The cables to the front panel USB 3.0 ports have external connectors instead of the proper header for motherboards. The adapter cost me an extra $10.

The lack of a reset button and the bright power/drive LED are minor annoyances.

Other Thoughts: Despite a few cons, this is an excellent case for a home server or multimedia machine.

4 out of 5 eggsSmall Sleak Simple

Pros: Small, High Quality, Black, Drive Bays work well, Places for drives everywhere there are 4 bays, 3 drives can fit on bottom, and under the drive cage you can fit another drive. Also fits a fullsize video card no problem. End result after hours of cablemanagement is a small sleak fully capable machiene. Weights a ton with everything in there.

Cons: PSU did not fit. I bought a extender kit from lian li. Also note that USB 3.0 comes terminated with stanard connectors not MOBO connectors. you need an adapter and the adapter i bought did not fit with the PSU above the mobo. I bought a slim cooler but the Stock one would have fit fine as well. CABLE MANGEMENT IS A NIGHTMARE IN THIS CASE.

Other Thoughts: Be ready to spend time on cable management. However im really pleased with size and system. I have 4 2TB drives for 8TB total plus a SSD and blueray drive. Fits everything for a sweet media center/server.

4 out of 5 eggsOverall great case

Pros: High quality case that was the size I needed for a new multi-purpose HTPC. The look of the case is very professional. The materials are high quality. The sides come off very nicely. I love having two 140mm fans in this size of case. They provide great airflow and are whisper quiet.

Cons: The USB 3 cables from the front of the case are not a USB 3 motherboard header plug, but two very long USB 3 cables which are designed to go out of the back of the case, loop around, and plug into USB 3 plugs on the back of your motherboard. This may have been acceptable for cases when USB 3 first launched (and motherboards may not have had the USB 3 header), but that is no longer the case. It looks like I may be able to separately purchase a proper replacement cable from Lian Li. For a new case in 2012 this was a bad decision.

Removing the HD bay seems like it will be semi-common for this case as there are three HD mounts on the bottom of the case. Be aware that removing this bay requires drilling out 4 pop-rivets which connect the optical bay to the HD bay. I had a drill so this was not too big of a con for me. If you don't care about keeping the optical bay than the entire thing just comes right out.

Other Thoughts: Even with the HD bay removed you still have to stay within the size spec on the PSU due to a very slight overlap of the optical drive bay. 160mm fits fine with the HD bay removed, but you need to keep the HD bay I would highly suggest a 140-150mm PSU. 160mm would give your cables almost no room to bend.

While stated on their site, if you use 3.5inch HDs on the bottom of the case you will not be able to fit a double wide video card. You will need to put the 3.5inch HDs in the HD bay in that scenario.
