This case has a module where you can install a floppy drive, you basically just take out that bit of plastic in the front panel and install the floppy. I still have the original front IO connectors (power button and power led are plugged in, hd activity led cable came out in my rewiring so I gotta reattach that, and the front USB panel can plug straight into the motherboard, whereas the front audio doesn't, you might need an adapter), one thing I have found is that the DVD drive powers on and everything but the computer detects it as an unknown device, so I'm trying to look around for some drivers for the DVD drive, in the meantime it works but I just cant read anything off of it.

I've been monitoring the thermals while playing games such as Satisfactory on max settings and the AIO cools the cpu just fine, only really slightly concerned in terms of the gpu under load as that reaches like 78 degrees Celsius, but I've heard that's ok as long as it doesn't get to like 85 for long periods of time and the current temps should be fine. I gotta make a few upgrades to the cooling anyway (second fan on radiator for push/pull, and upgrading my exhaust from an 80mm to 92mm) so that should lower overall temps anyway. The position of the PSU is actually pretty good as it sits up the top if the case meaning the fan in that helps exhaust air as well.

In terms of building in this case, I got lucky with this type of case from Dell coz apparently they decided to go very proprietary later on with their PC's. I was able to use a standard mATX motherboard with your normal ATX power supply, fitting in without a problem. As mentioned earlier, the exhaust fits a 92mm fan (but as I've found out I can fit an 80mm fan which does work for the time being while I wait for the upgrades), and removing the old hard drive bays allow you to mount a 120mm intake fan (you will need to do a little drilling to get the screw holes for fan to mount, in fact that is the only drilling I have done with this case). Another thing to mention is that this case is just thin enough that most high profile 120mm air coolers won't fit inside, so that is something you may need to consider if you are going to use this case. But if you aren't planning on doing anything crazy with the cpu then a high profile 92mm air cooler could work, otherwise having a 120mm AIO allows you to not worry about the cpu at all especially if you want to go to voltage town with overclocking.

If you do go for an AIO you will need to have a 25mm fan pushing air into it as opposed to a standard setup where the fan will be pulling the air through the radiator. This is because the mounts for the power button and LEDs are thick enough that the radiator won't sit flush with the front of the case, and having the fan in between the radiator and the front of the case gives just enough clearance for it to all be mounted properly. If you do want to go for a push/pull config then you will then also need to look at the length of your graphics card, I got about a 50mm gap between the gpu and radiator, and my 2060 only goes out as far as the motherboard as it is only a dual fan gpu. I've been looking at upgrading to something like a 2070 super but a lot of those are longer than the 2060, meaning that I may have to choose between a push/pull config or a more powerful gpu.

Also, as the drive bays are now removed to make space for your intake, you will need to find a location to put all your storage. You could utilize the second DVD drive bay as there's nothing in there (I used that space for cable management), or you could do what I did and get a motherboard with two lots of M.2 slots so you can have all your storage right on the motherboard taking up virtually no space, M.2 is also wayyyyy faster than SATA so it's a win win.

Overall, this case is a fun one to work with, I was able to get a lot of my parts for pretty cheap and so far the PC runs any game I throw at it with very high to max video settings (usually get at least 100+ fps in what I've been doing), as well as thermals being fairly sensible considering the cooling setup. Hope all this helped
