How much does it cost in computing time/hardware to mine bitcoins?: I'd like to know how much the number changes...

It really depends on how much you're willing to spend. Low end Let's talk about the very smallest investment you could make for mining bitcoins: a Raspberry Pi. It can do 200,000 hashes per second, which might sound like a lot, but actually it's about 0.000001% of the total network hashrate. Power: 3.75 W Hashrate: 0.2 MHash/s Cost: $35 (Note: this doesn't mean a RPi is useless for mining. You can use it as a host for your ASIC/FPGA miners.) Mid range Okay, CPU mining is bad, but what if we use GPU's? Let's say we use a $162 graphics card, the 5830 from AMD. Let's throw in another $187 for case/motherboard/power supply. (Based off of this list I just threw together.) Power: 175 W Hashrate: 302 Mhash/s Cost: $349 High end Okay, let's get something specifically designed for bitcoin mining - the ModMiner Quad. It costs $1070, but it needs a host, so let's use a raspberry pi f...
