Phanteks Eclipse G300A - got tired of looking at my girlfriend's ancient beat up Antec P1. The Phanteks is a solid case for $50, less if I get the rebate. Would have preferred to pay another $10-15 to get it with more than one pre-installed fan, but I have a ton of 120mm fans laying around, so this is just laziness on my part.
Installed 2 front and 2 top fans, plus the rear it came with. Will probably add a third front at some point, just couldn't find a 3 way power splitter when I was putting it together last night. This replaces an Intel Z270 setup (don't remember the exact CPU right now) -
Ryzen 5 3600 CPU
Thermalright Peerless Assassin HSF (new)
ASUS TUF Gaming X570-Plus WiFi ATX motherboard (new)
32GB DDR4 (slow, will replace it with 3600 when my other kit gets back from RMA)
500GB Samsung 850 SATA SSD
4TB WD HDD
2x1TB Intel 670p NVME SSDs
Zotac GeForce RTX 2080
Rosewill Capstone 1000w modular PSU
It's quiet and runs very cool.
Seriously considering putting my build in this case for better cooling (just swap the CPU, GPU, and drives - they're both X570 boards with two NVMe slots) but her HDD won't fit in the A4-H20 case. I may just put it in an enclosure.
Also picked up a Thermalright 240mm AIO - have to decide if I'm using it in the ITX case to replace the current AIO or swapping things around... If I do the latter I'll return it for a 360mm version.
