I'm a fan of the ASUS Chromebox hardware, specifically the M004U with the Celeron 2955U processor. Comes with 2 GB of RAM, and 16GB SSD. It typically retails for $160 USD. I have a couple running Linux (HTPC and a desktop for my kids).
I picked up a third one on black friday for $110 just to play with, was specifically interested in loading OpenBSD on it. 5.6-stable doesn't work because of the lack of USB 3.0 (xhci) support, but 5.6-current installed without issue. The wireless adapter wasn't detected, but the Realtek ethernet device works. I have it driving a 1920x1200 display over HDMI. It's been a long time since I've used OpenBSD as a desktop so I've got a bit to figure out, but thus far this little system is running very nicely. Just in case anyone else is interested in it I'm including dmesg output. Also, if you do try just be aware that the Chromebox has to be put into developer mode and the default BIOS will need to be replaced with coreboot. The Kodi (XBMC) wiki has a good document on doing that. http://kodi.wiki/view/ASUS_Chromebox dmesg output: OpenBSD 5.6-current (RAMDISK_CD) #584: Mon Dec 1 00:41:23 MST 2014 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/RAMDISK_CD real mem = 4215820288 (4020MB) avail mem = 4102762496 (3912MB) mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0x7f69f020 (7 entries) bios0: vendor coreboot version "4.0-7445-ge0d42b6-dirty" date 12/02/2014 bios0: Google Panther acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SSDT MCFG APIC HPET SSDT acpimadt0 at acpi0 addr 0xfee00000: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: Intel(R) Celeron(R) 2955U @ 1.40GHz, 1397.00 MHz cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUS H,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,SSE3,PCLMUL,DTES64,MWAIT,DS-CPL,VMX ,EST,TM2,SSSE3,CX16,xTPR,PDCM,PCID,SSE4.1,SSE4.2,MOVBE,POPCNT,DEADLINE,XSAVE, RDRAND,NXE,PAGE1GB,LONG,LAHF,ABM,PERF,ITSC,FSGSBASE,ERMS,INVPCID cpu0: 256KB 64b/line 8-way L2 cache cpu0: apic clock running at 99MHz cpu at mainbus0: not configured ioapic0 at mainbus0: apid 2 pa 0xfec00000, version 20, 40 pins acpiprt0 at acpi0: bus 0 (PCI0) acpiprt1 at acpi0: bus 1 (RP01) acpiprt2 at acpi0: bus 2 (RP02) acpiprt3 at acpi0: bus 3 (RP03) acpiprt4 at acpi0: bus -1 (RP04) acpiprt5 at acpi0: bus -1 (RP05) acpiprt6 at acpi0: bus -1 (RP06) acpiprt7 at acpi0: bus -1 (RP07) acpiprt8 at acpi0: bus -1 (RP08) pci0 at mainbus0 bus 0 pchb0 at pci0 dev 0 function 0 "Intel Core 4G Host" rev 0x09 vga1 at pci0 dev 2 function 0 "Intel HD Graphics" rev 0x09 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) "Intel Core 4G HD Audio" rev 0x09 at pci0 dev 3 function 0 not configured xhci0 at pci0 dev 20 function 0 "Intel 8 Series xHCI" rev 0x04: msi usb0 at xhci0: USB revision 3.0 uhub0 at usb0 "Intel xHCI root hub" rev 3.00/1.00 addr 1 "Intel 8 Series MEI" rev 0x04 at pci0 dev 22 function 0 not configured "Intel 8 Series HD Audio" rev 0x04 at pci0 dev 27 function 0 not configured ppb0 at pci0 dev 28 function 0 "Intel 8 Series PCIE" rev 0xe4 pci1 at ppb0 bus 1 re0 at pci1 dev 0 function 0 "Realtek 8168" rev 0x0c: RTL8168G/8111G (0x4c00), msi, address c4:54:44:4d:be:ab rgephy0 at re0 phy 7: RTL8251 PHY, rev. 0 ppb1 at pci0 dev 28 function 1 "Intel 8 Series PCIE" rev 0xe4 pci2 at ppb1 bus 2 "Atheros AR9462" rev 0x01 at pci2 dev 0 function 0 not configured ppb2 at pci0 dev 28 function 2 "Intel 8 Series PCIE" rev 0xe4 pci3 at ppb2 bus 3 "Intel 8 Series LPC" rev 0x04 at pci0 dev 31 function 0 not configured ahci0 at pci0 dev 31 function 2 "Intel 8 Series AHCI" rev 0x04: msi, AHCI 1.3 scsibus0 at ahci0: 32 targets sd0 at scsibus0 targ 0 lun 0: <ATA, SanDisk SSD U110, U221> SCSI3 0/direct fixed naa.5001b44bed91e41e sd0: 15272MB, 512 bytes/sector, 31277232 sectors, thin "Intel 8 Series SMBus" rev 0x04 at pci0 dev 31 function 3 not configured vendor "Intel", unknown product 0x9c24 (class DASP subclass miscellaneous, rev 0x04) at pci0 dev 31 function 6 not configured isa0 at mainbus0 com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo uhidev0 at uhub0 port 2 configuration 1 interface 0 "Logitech USB Receiver" rev 2.00/29.00 addr 2 uhidev0: iclass 3/1 ukbd0 at uhidev0 wskbd0 at ukbd0: console keyboard, using wsdisplay0 uhidev1 at uhub0 port 2 configuration 1 interface 1 "Logitech USB Receiver" rev 2.00/29.00 addr 2 uhidev1: iclass 3/1, 17 report ids uhid at uhidev1 reportid 2 not configured uhid at uhidev1 reportid 3 not configured uhid at uhidev1 reportid 4 not configured uhid at uhidev1 reportid 16 not configured uhid at uhidev1 reportid 17 not configured "\M-1???\^D??\^A??\^P??????@????\^A?? \M-1???\^D??\^A??\^P??????@????\^A??" rev 1.10/0.01 addr 3 at uhub0 port 4 not configured umass0 at uhub0 port 7 configuration 1 interface 0 "Generic USB Storage" rev 2.00/2.60 addr 4 umass0: using SCSI over Bulk-Only scsibus1 at umass0: 2 targets, initiator 0 sd1 at scsibus1 targ 1 lun 0: <Generic, Power Saving USB, 0260> SCSI0 0/direct removable serial.05e30727000000000260 sd1: 7580MB, 512 bytes/sector, 15523840 sectors softraid0 at root scsibus2 at softraid0: 256 targets root on rd0a swap on rd0b dump on rd0b syncing disks...
