I currently have an HP omen obelisk 875-0035qe that I got for $1,000 used. It has an Intel i7-8700 with an rtx 2080 but has a stock Intel cooler and a pretty basic HP motherboard. I don't have many issues with this build but the cooling 
is actually horrible. I've been wanting to do a case swap and maybe get an AIO water cooler for my cpu. Any recommendations for a cheap good looking case / water cooler?image.png.0324905b677d788c0657f0723ab82601.png

Fractal Meshify C with a 280mm+ AIO.


HP Edoras micro-ATX is the motherboard, as stated below by @SpookyCitrus.  May be an issue fitting it in the Meshify, not sure tho.

I believe the Obelisk(like all of the Omen line) uses an HP proprietary motherboard so you would likely have to get a new mohterboard as well, possibly even a PSU. As those two parts other than the case are not standard and will not work in a standard case. The PSU may fit but it more than likely uses a non standard 24pin or connectors.

If you ask for a Mid Tower case recommend, I will 90% of the time recommend the Fractal Design Meshify C or S2.

I was looking at water cooling on the same HP Omen but as the motherboard has to come out to achieve this I just swapped the HP Omen in to a Corsair Carbide Series 275R Mid-Tower ATX Gaming Case using the stock motherboard and added a Cooler Master Hyper 212 EVO CPU Air Cooling System with no issues, and all for about the same cost as a decent 240mm AIO water cooling system,  It now has 3 intake and 2 exhaust 120mm fans (had added a couple of extra fans to the Omen before), there are no additional fan headers so I have had to use splitter cables.

I chose the Corsair as the configuration of 2 x USB 3, power and audio sockets on the top of the case was as close to the HP Omen as I could find. Only the reset button on the case is redundant. I haven't fitted the Omen light board as I'm not to fussed about it but I may get around to it just to see if I can. 

The hardest bit was removing the CPU cooler back plate as HP glue it to the motherboard. Just took my time and gently prised it off with a butter knife!

Before the CPU would hit mid 90's playing Warzone for 25 minutes, since the case swap it sits at 73 max.

Finally put the light board in. Not sure it adds anything but I'm still pleased with the temperature reduction
