Antec GX505 Window SC Mid-Tower Case Review


<< PREVIOUS            NEXT >>

Final Thoughts

Overall I found the Antec GX505 Window SC to be an adequate budget gaming case. There are some issues with the design that I personally did not like. The inclusion of the 3.5″ floppy drive bay is a waste of space. Antec should of used this space for another 2.5″ SSD bay instead.

I found the use of twist ties and pop out PCI slots to be a bit on the cheap side. I’ve reviewed other cases in this price range that did not skimp out on the zip ties or the PCI brackets.

Also, this case is strictly for those that are using air cooling. It is a budget case, so that is fine. If you really wanted to set up a case for water cooling there are numerous other options that will allow you to do that properly, and the GX505 Window SC is not one of those options.

On the plus side of things, the amount of drive options and inclusion of 3 pre-installed 120mm fans should suffice for most gaming set ups. I personally only use 2 HDD drives and 1 optical drive for my gaming PC.

The Antec GX505 Window SC is also very light. It weighs in at 10.8 pounds. This may not matter to some, but for others after building a PC, the weight can add up, and thankfully this case is not going to add that much more to the total.


Antec GX505 Conclusion

The performance of the Antec GX505 Window SC should be fine for anyone needing an inexpensive budget gaming case. I personally think there are other cases that do better in this price range, but it will get the job done.

The GX505 Window SC aesthetic redesigned panels look pretty cool. I think it’s a big improvement over the GX500. Granted aesthetics do little for a cases function, but when all other things are equal, the looks of a case can be the clincher.

The construction of the Antec GX505 Window SC is good. Considering how light the case is, it doesn’t feel flimsy at all.

The functionality of the Antec GX505 Window SC is a bit of a mixed bag. The inclusion of a 3.5″ floppy drive mount, and the HDD rail system doesn’t allow the use of 2.5″ SSD’s. The mounting for the two possible SSD locations are not tool-less either, which isn’t terrible, but Antec went through the trouble to design the rest of the case to be tool-less then dropped the ball with the SSD drive mounting systems.

Then you have the nagging issue of the front fan filter. Every time you want to clean it you are going to have to remove the front panel to get at the filter. Also, if you use the front panel LED, you are going to have to possibly unplug it, or be very careful not to yank the wire and break it.

Available online for $69.99 (Amazon), the Antec GX505 Window SC is a competitive value in the budget segment of cases they are marketing it against. Retail price is likely to be lower, but I can’t say for sure.

Antec did cheap out a bit with the twist ties and knock-out PCI expansion slots, which makes me feel the value of the case should be slightly less. Granted, twist ties are probably not a huge deal to others, but I really did not like the cheap knock-out PCI expansion slots.

I have used a few different Antec cases for personal PC’s, and this one is hard for me to recommend. The GX505 Window SC does everything it’s suppose to do, but that’s it. It’s a normal case with some cool looking aesthetic panels.

If you just need a basic case that happens to look cool, and do not mind the faults of this case, then I’d say check it out. Otherwise, I would pass on this one, and look at other cases in this price range that do things just a bit better than the Antec GX505 Window SC.


+Built-in fan controller
+Light weight case
+Dust covers for front audio and USB ports


-Front dust filter is annoying to get to
-Wasted space for a 3.5″ floppy drive
-2.5″ drive installation is not tool-less


  • Performance: 7.50
  • Appearance: 8.25
  • Construction: 8.75
  • Functionality: 7.00
  • Value: 8.00

Final Score: 7.9 out of 10.

    Have you considered the possibility that what you call a 3.5″ floppy slot is actually where most folks would mount a 3.5″ card reader?

    1. Jason Maxfield

      You could mount a 3.5″ card reader there. You can also mount a 3.5″ card reader in a 5.25″ slot, since you can get adapters, or even have adapters already included with a 3.5″ card reader. With the brackets already part of the cage, that space is limited in function, and that is my main gripe about the 3.5″ slot.

  2. Himanshu Rawat

    I am unable to screw my GPU (zotac GTX 960) after mounting on the PCI slot. How to fix the GPU in that position any solution?

    1. Jason Maxfield

      This particular case doesn’t have brackets screwed on like most other cases. The brackets have to be popped out to place anything in the corresponding PCI slots lining up with your motherboard. Antec did include screws for the PCI mounting locations once the tabs are popped out.

      Sorry for the late response, I never received the alert in my email for this comment.

    Horrible review. 5.25 is not just for floppy smh. and the ssd spot use thumb screws and its still tool less. just saying.

    1. Jason Maxfield

      Mike, I never said 5.25 was just for floppy. I referenced the 3.5 as a ‘floppy drive mount’. Obviously you can put a card reader in that section. The SSD bays did not use thumb screws. I recently gave this case to a friend for better air flow over her old case, and I installed everything for her.

      Thanks for the feedback.

    Do you think h100i gtx will fit on the top?


    I’m seriously thinking of buying H100i GTX for my config.

    1. Jason Maxfield

      Lemor, I think if the H100i GTX were to fit at all you would have to install it in a pull configuration. The top section of the chassis has just enough room to mount two 120mm fans. The radiator for the H100i GTX is 276mm wide and would not fit in the top where the fans mount.

      However since the fans are almost flush with the top of the case, there might be room for the 30mm thickness of the radiator below the fans. Antec’s information about water cooling for this case is non-existent. Tech specs mention water cooling grommets and that’s it.

      Careful measurements will be your best guide, if you already own the case. If you have other options open, I would look for a case that specifically lists compatibility with the H100i GTX to ensure a proper installation and functionality.

      1. lemor

        I just check the information you provided. The top fans are just above the motherboard. But there is space below the fan and above the mobo. Any modding advice you would suggest?

        1. Jason Maxfield

          There is space below the fans since the fans are mounted above the roof of the case. Just how much space, that is the question. A lot of how things will fit depends on your motherboard and where your 4/8 pin CPU power are located. The thickness of the radiator could interfere with the 4 pin headers for CPU fans and DIMM slots as well.

          Careful measuring and looking at the layout of your motherboard is all I can suggest to see if the H100i will fit in the case. Also, you might lose out on the top-most 5.25″ drive bay, depending on the orientation of the radiator once installed.

          1. Lemor

            Alright I’ve purchased the radiator. I’ll give it a shot. If it doesn’t work I’ll remove the top cover over the two 120mm(s) and mount them in push pull config. None the less pull (intake).

            Or I’ll buy a new case. What would you suggest?

            1. Jason Maxfield

              Any suggestions I might make would depend on if the cooler fits the case or not. Just have to see what happens.

    Hello Jason , Do u think that a ASUS GeForce GTX 1070 ROG Strix Gaming would fit into this case? A quick reply would be very much appriciated! //Joel

    1. Jason Maxfield

      Sorry for responding late. My notifications keep ending up in my spam folder… Gmail is being bad.

      Anyhow, to answer your question, the Asus 1070 ROG Strix will fit in that case easily. I checked the specs on the case and it can accommodate GPU’s up to 14.95″ long. The Strix is just under 12 inches.

      The way the Antec GX505 is designed leaves room for long GPU’s since it doesn’t have a drive bay in the way, where your typical single GPU will be seated on your motherboard. This also allows the front-top 120mm fan that is included to blow air directly at your GPU to help keep it running cool.

    can i fix RX 480 in this casing…??

    1. Jason Maxfield

      It depends on which RX 480 you intend to use in the case? Although, as I mentioned in a previous reply, the case can accommodate GPU’s up to 14.95″ in length. The PowerColor Red Devil RX 480 is about 12.2 inches long, and I believe it’s one of the longest RX 480’s on the market, and that one should fit just fine in the GX505.

  7. Emily Stone

    I’m struggling to find much other info on this case online. Did you have any issues getting your fans (other than front, controlled by top switch) running? I haven’t been able to get the other two going.


    1. Jason Maxfield

      Hi Emily,

      I don’t recall how many leads were on the fan connector for the switch. I think the 2 front fans and the rear exhaust were already hooked up to the fan switch. I don’t think there was room for any others. You could use a Y adapter to hook more fans up to the controller.

      Otherwise, you can connect extra fans directly to the motherboards fan headers. With most modern boards you can also set fans to spin (in the BIOS/UEFI) at certain percentages based on thermal output of your CPU or system temps. Using a combination of both you can probably find a good mix of air flow to noise while keeping everything running cool.

  8. Crazed

    I know this is super old but do you know what kind of pins did the fans have? My motherboard has only 1 chassis fan connector, is there any way I can still run all 3?

    1. Jason Maxfield

      You can get a molex to 3 pin adapter for powering the fans. Might need two of them, or one with a Y connector to hook two up to one lead.
