It's not another A3 :)
Recently downsized from an AP201 (33L) to a Zalman Cubix (17L) for my living room "steam machine". For 60$ CAD I have no complaints, and with some quality of life updates (ie. front fan mount points, full side panel ventilation), Zalman has a real sleeper on their hands for unassuming, no frills, compact living room type PCs, imho.
My modest specs: Seasonic Focus 650W, MSI Pro B550M-VC Wifi, 5700X3D, RX6700XT (max gpu length is 275mm), Thermalright SI-100, 32GB DDR4 3600, 1TB M.2, 80mm fan as exhaust, 120mm as front intake (both static @ ~1000rpm).
I might clean up the cabling a little more at some point, but as none of it is visible externally I'm not exactly pressed.
CPU temps are generally mid 60's to low 70s depending on the game and settings, GPU temps are a bit higher.
