So, I have decided that I need to have a way to test some ideas while at home. Since there will be bunch of people chiming in, I will make it structured: Speclets: 128GB RAM 4TB+ hard drive Drive mirroring Headless (single VGA monitor sufficient) Linux Constraints: Price: it's for home so I don't have an expense account Size: it's a Manhattan apartment, so space is limited My options as I see them: build my own from parts. There seem to be specs kicking around the web that would allow me to build a server like that for about $1500 (since I don't care about video). Sounds like a hassle though and I have to pick the right hardware buy a refurbished server on Newegg or something like it. It's apparently possible to get a reconditioned server or workstation with 128GB of RAM for $600-$800, adding nicer SAS disks would be another $200, so I can get a very spiffy box for about 1k. Rack-mounts seem to be cheaper for the same specs, but they need more space.
