1U server for 500 bucks
Unreal? Actually, if you assemble it yourself and choose the right components.
And now the slides:
Case AIC RAC1E-F01 :

Cost 4000-4500 rubles.
Riser card 1x PCI-32 RC1-009E : Cost

600-700 rubles.
TTC-NK54TZ fan for 775 socket :

Cost 370-440 rubles.
Motherboard Giga-Byte GA-945GCM-S2L :

Cost 930-1200 rubles.
Processor Intel Celeron CPU E1200 TDP 65W
Cost 1200 rubles.
Memory DDR-II 512MB
Cost 200-300 rubles.
HDD 80Gb
Cost 1000-1200 rubles.
The cost of the whole set is 8300-9540 rubles. If you take a buck for 25 rubles, you get the price 332-381 bucks. If you need a stub on the connectors of the motherboard (the standard stubs that come with the motherboard will have to be brutally cut), then you need to throw another 500-600 rubles.
The maximum cooler can dissipate 105 watts. Enters the housing only without a fan. The TDP of the processor used is 65 watts. When testing the thermal conditions at full load, the margin to the throttling temperature is 10 degrees.
UPD:
I was asked to write about tasks here. From my point of view, it can perform the following tasks:
1. Firewall, proxy server. The bandwidth will be on the order of 100-200 Mbit, maybe more all depends on how the traffic is processed.
2. IP-PBX (Asterisk). According to the estimates from the developers, such a piece of hardware should draw 30 simultaneous conversations (E1). True, the board will be twice as expensive as the server :)
3. DHCP / DNS server. Here you can put weaker hardware up to epia
4. Web server for development.
5. The mail server.
UPD2: A little explanation, for those who advocate for real servers. It is only a low-end sector. If you need more reliability or less maintenance problems, buy a normal branded server. Assembling the server is recommended only to those who understand what they are doing and understand why he does it.
PS Prices were taken from price.ru so in reality it can come out more expensive.
