One of the systems commissioned earlier this month was a Core i3 2120 Fedora test system and this newest system added today is a similarly speced system, but this time is being added to the Ubuntu collection of systems running the latest mainline Git kernel on a daily basis. This system was powered by a Core i3 2100. The i3-2100 has a 3.1GHz base frequency and is dual-core plus has Hyper Threading. There's HD Graphics 2000, but this system is just running Ubuntu 15.04 Server.
The Core i3 2100 was used for today's build as it was the last of my older Sandy Bridge CPUs without a system to run on, and wanting to get it running in something before Sandy/Ivy Bridge motherboards are no longer easily available through retail channels... An issue I've run into with some slightly older Intel Extreme Edition / Xeon / Opteron processors with having some moderately powerful processors but no longer having working motherboards and not being able to easily find quality replacements.
The motherboard for this build was a MSI H61M-P31/W8 micro-ATX motherboard. This is my first time using a MSI H61M board, but it's been working out fine so far as would be expected for a few year old product and using the Intel H61 chipset. This micro-ATX board can be found for around $40 USD today and has dual DDR3 memory slots, one PCI Express 3.0 x16 slot, four SATA, etc. It's decent, low-cost, and suits my needs for just running benchmarks every day.
Other components for this build were 2 x 4GB of OCZ DDR3 memory, Serial ATA 3.0 Seagate Barracuda 500GB HDD, Thermaltake i1 Heatsink, EVGA 430W PSU, and this 2U case.
So far things are working out well for this build. You'll begin to see it being used alongside many other systems for the fully-automated, daily performance benchmarks of the upstream Linux kernel Git over at LinuxBenchmarking.com with this performance tracker. This i3-2100 system is another one of the test systems running on Btrfs for its root file-system as another point to make this older Sandy Bridge era system more interesting.
