  1. This is the best case I have ever had the pleasure to work with

    Posted by Propanelgen on 24th Mar 2014

    The quality and finish of this case is extreme.
    I ordered it flat packed, and assembling it was very easy, even though I had to peek at the manual on a couple of occations.
    I'm just blown away by all the thought Caselabs has put into the design of this case, the options you have in building your rig seem endless.

    If there is something I wasn't satisfied with, it's the clips that hold some of the panels in place.
    About 50% of them were too lose, but they did include a bag of replacement clips.
    However, no reason to replace the clips, all you have to do is remove them from the case, bust out the pliers to tighten the clip and then reattach it to the case.

    No regrets about ordering it flat packed, I find much joy in assembling things myself :)

    If I ever order a new case (this one seems it will last forever), then surely I will order it from Caselabs!

  2. The pics do not do it justice. Epic doesn't come close.

    Posted by Luke on 28th Feb 2014

    This. Thing. Is. Monstrous. And it's not even their biggest. The case this is replacing fits inside(before i put the kit in) and I shut the door with room to spare. It's like seeing a picture of a giraffe, then actually standing next to one, and looking up, wondering how in the world they got so tall.

    This is my last case. I don't see myself needing bigger, but IF I ever do, I'll be coming back here.

    It came pre-assembled. I feel bittersweet over that. I kind of looked forward to putting it all together myself, but it did save me half an hour+/-. Solid construction. Dead sexy matte black. All you have to do is throw on the feet/casters(if you ordered them) and start picking where you want your kit to go. And believe me, the choices are endless.

    I honestly can't wait till stage two where I fill in some of my empty gap with radiators/res/pump instead of just a few fans.

  3. Just what I needed for my development workstation platform ...

    Posted by jack labout on 14th Oct 2013

    This box is where my Asus X79-Deluxe motherboard and 4930K CPU is going to live.

    I picked this box because it will mount long ATX (XL-ATX = quad-SLI or 4-way Xfire) and because I can "stuff" a dual-CPU, SSI-EEB motherboard into it, albeit the latter has to be "stuffed" onto the ST10's mounting tray very carefully.

    And because I am going to be running multiple virtual machines on the hardware, having the room to add extra hard drives without restricting radiator space, or vice-versa, is also an excellent feature.

    The ST10 case is exactly what anyone running PCIe 3.0, dual, tri, or quad graphics card configurations needs to hold all his/her hardware plus the requisite cooling as it will hold two 120.4 80mm thick radiators without having to mod the case.

    CaseLabs makes other cases that could do the job better, maybe, but they all cost a lot more money. The ST10 case gives the biggest bang for the lowest cost, which is why I bought mine.

  4. where can i start, just crazy beautiful

    Posted by ashraf on 15th Sep 2013

    from the package and until building it, its amazing and smart its like the case has its own personally.

    manual could include a bit more details, but still easy.

    con: i wish the power supply bottom mount was levelled was lower , i felt it took more space then needed, i didnt see the reason for it to be so higher different then eating space level.

    i wish the mount was levelled teh bottom because no one will put fans on there, only radiators. it also ate more space between my mobo and power supply for more tubing route. im planning to cut it so i could mount it the case bottom floor level, more space for me to work with .

    best case in the world for me because i understands me and what my goal is... (just wish power supply mount was left like sm8 floor level, but another then that its my baby...)

  5. Quality!

    Posted by Unknown on 18th Aug 2013

    The best package i`ve ever seen! Top quality, very solid and offer everything you need for your high end build!

  6. Imagination

    Posted by MNKyDeth on 12th May 2013

    This is a large case, buy the casters.

    Other than that all I can say is my god I wish I found this case sooner. Three rads, 5.25 inch double bay res 19 fans later I have a start to my new system.
    I keep finding more things I just want to add to this case.
    Really, you're imagination is the limitation of this case.

  7. Awesome case!

    Posted by Bernie on 5th May 2013

    Moving up from Corsair 650D and what a difference. Researched several cases, including a couple of the Magnum's from CaseLabs which were a little out of my budget. Decided on the Merlin ST10 and I am glad I did. Plenty of room and cable management is way better than most other cases I looked at. Great buy, great case, great company!

  8. the simplicity is amazing

    Posted by Omar Y. on 14th Apr 2013

    The case is just amazing!

    there is nothing fancy about the case but it is pure design genius.

    Honestly no matter what i decide to do next be it go with a large build with multiple loops or a smaller build i will never need another case.

    this case can do anything. Case-Labs you rock!

  9. Fantastic case

    Posted by Iqbal517 on 14th Mar 2013

    This case is an engineering marvel in quality and utility. Worth every cent, thank God we still have american companies with this kind of manufacturing quality. Highly recommended for serious water cooling enthusiasts. Don't think too much about just get one you won't regret it.

  10. Stunning, has to be seen to be believed!

    Posted by Scarecrow23 on 5th Feb 2013

    So mine arrived today and i've just finished putting it all together.

    All I can say is WOW.

    Starting with the packaging, you could see the level of thought, care and attention to detail that comes from CaseLabs. Everything was individually wrapped and clearly marked, so even an idiot like me couldn't go wrong.

    As you assemble it, piece by piece, and it begins to resemble a PC case, you just realise why these cases are worth every cent. Everything fits perfectly, nothing is difficult, everything just does what it should and looks stunning doing it. The case just has an aura of quality I haven't seen before.

    I am coming from a Cosmos 2 and while the ST10 is bigger (quite a bit with the casters on) it is lighter and well, better in every way. Having owned an Cosmos, 800D and TJ11 previously, nothing comes even close to the finish and design of the ST10.

    Shipping to Australia took less than 2 weeks from placing the order, and Jim was fantastic and helpful when i changed from my initial SM8 order (because we all need more space right?).

    Anyway, that is enough gushing about this case, but if you own a CaseLabs case, I am sure you understand. If you don't, go buy one, NOW!!!

    Time to start my build. Monstas Incoming.
