$180 HP Stream Mini Desktop with Intel Celeron 2957U, 2GB RAM, 32GB SSD storage.
$320 HP Pavilion Mini Desktop Intel Pentium 3558U, 4GB RAM, 500GB SSD storage.
$450 HP Pavilion Mini Desktop Intel core i3 4025U, 4GB RAM, 1TB SSD storage.
While they all not fanless PC, their CPUs designed for laptops not for tablets like Z3537f, but advantage from those CPUs you will get USB3.0 and Gigabits Ethernet and support RAM more than 2GB.
Such like HP Stream mini ($180) it's RAM upgradable to 16GB, SSD storage also upgradable via SATA port and it come with Free Windows 8.1 with Bing 64 that should mean to 64 bits UEFI. (Also come with USB Keyboard)
I think it's pretty a good choice compare to those Chinese mini PC box especially compare to Z64W with Windows that cost around ~$150+.
