What sort of bargain-basement ram are you shoehorning into that budget? The cheapest 4gb DDR3 I see is $70 a pair, and the names I've heard of are $100, so that's:
$210-300 in RAM
$600 in processor
$260 in mobo (cheapest mobo on newegg with six ram slots, LGA1366, and dual gigabit--there are only 4 that aren't refurbs)
$85 SSD
$80 pair of cheapo 500gb drives
That's $1235-1500 with just the components you listed. You haven't mentioned power supply, case, cables, etc. It also seems like you're seriously skimping on the data drives vs the rest of the build.
I assume this is for edubuntu or similar, why so much ram?
Quote:
Processor: Core 2 Duo or Core 2 Quad as recommended minimum. Simpler CPUs will work, but at a performance penalty.
Memory: 512MB for the server itself, and between 256MB and 768MB of RAM per client, depending on the demands of the users. Typically, you would want at least 4GB RAM for 20 LTSP users, and ideally at least 8GB. Note that you can also use local applications (called local apps) to shed some memory usage to the thin clients.
Disk: 10GB Depending on options. It's recommended that you keep the /home partition on fast disks for optimal performance, refer to the post-install section in this document for more information on setting up a home partition on RAID.
Network: LTSP can be very demanding on local network resources. It is recommended that you have at least 1 gigabit connection to the server for every 15 thin clients, and at least 100mbit connections to the thin clients from your switches.
