Verdict
Jonsbo Z20
7.5 / 10 Expert Rating
A solid alternative to the D31 Mesh for builders who want a bit more radiator headroom and a more conventional mesh look at a similar budget price.
MSI MPG Gungnir 300R
7.5 / 10 Expert Rating
Excellent fan-count value for a glass showcase case, just double-check your GPU length against the tighter clearance.
