I just ordered the A4-H2O at caseking, I wanted to share the story here.
Edit: my order has been shipped, 3 hours after I ordered
I had to replace my beloved A4-SFX when I could order a 3-slot 3080 in Dec 2020. I had to rebuild into a NR200P that I do not love as much as my shoebox. The plastic clips holding the panels can break easily and Cooler Master does not sell them individually. Also, my Corsair SF750 broke in my NR200P. I could not find the rootcause, the cord extension makes some worrying noise when replugging the cable on the NR200P. Maybe my PSU just died for another reason, but it did not make me love the NR200P more.
When I go on trips, I love to bring my SFF with a portable monitor instead of using a super loud and hot gaming laptop.
We could not go on vacation for the last 2 years due to... you know what, so the NR200P never made a trip.
Yesterday, I tested my wife. I showed her the NR200P and the A4-SFX and asked her if she was ok with me bringing the NR200P in the car trunk. She laughed at my face. She said if I only brought with me 1 pair of pants and 2 T-Shirts, yes I can pack the NR200P. But the A4-SFX is fine, it fits in my backpack.
So this morning, I ordered the A4-H2O from caseking with a Phanteks 240 to rebuild my system in as is. I hesitated between rebuilding the A4-SFX + keeping the NR200P with a CPU+MB upgrade and switching to the H2O.
First option is tempting now that we can order GPUs easily, but prices for medium GPUs remain really high.
