關於那一台作為遙控的電腦，具備 AST2400 的主機板該是比較方便和便宜：

The AST2400 provides a 2.5GHz PCI-Express interface. The AST2500 supports PCI-Express 2.0, which is compliant with PCI-Express Base Spec. Revision 2.0. The PCI-E bus controller connects to the VGA Controller that allows for direct communication with the 2D Graphics Engine, SPI Host Controller, and P2A Bridge.

Intel C220 系列晶片組的 TDP 只有 4.1W：

基本上就是這些 Supermicro 的主機板比較好買：

價格方面則不會超過 ¥400 的說：

然後看看所有 Xeon 處理器，TDP 最低的型號只有 13W：

就是這一顆沒有內建 GPU 的 E3-1220L v3，正好適合 C220 系列的晶片組，而且 Haswell 也是 Intel 史上第一代支援 AVX2 指令集的處理器，因此絕對可以跑那些 x86_64‑v3 的軟件：

https://www.techpowerup.com/cpu-spec...1220l-v3.c1642
With a TDP of 13 W, the Xeon E3-1220L v3 consumes very little energy. Intel's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1600 MHz, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, Xeon E3-1220L v3 uses a PCI-Express Gen 3 connection. This processor lacks integrated graphics, you might need a graphics card.
價格方面也是超級便宜，但是選購的時候千萬不要買那個 80W 的型號：

With a TDP of 80 W, the Xeon E3-1220 v3 consumes a good deal of power, so decent cooling is needed.
