Litecoin mining is the most popular
but there are many other scrypt based coins:
Feathercoin, Worldcoin, digitalcoin, Megacoin, to name a few.
If you want an overview of PC building start here.
Want to get a ton of GPUs with a single motherboard? Many people don't know you can use PCIe extenders to hook PCIe x16 GPU cards up to a PCIe X1 slot. Many motherboards have multiple PCI Express ports, some have as many as 5. Remember to get two power supplies or more for more than two GPUs! At this point in time we also recomend that use FM2 socket motherboards for the new A-Series AMD cpu. It will save you money over the Intel versions.

There are a few basics to understand if you have never built a PC. Modern PC components fit together like Legos and it is a trivial task to assemble a PC given that you have compatible components. There are several basic components you will care about: Motherboards, CPUs, Memory, Power Supplies, Hard Disks, CD/DVD Drives, and GPUs.
First of all you need to get a motherboard with many PCI-e slots (where you plugin your GPUs). Each motherboard we recomend has an FM2 socket (a place where you plug in the CPU) so you will need to buy a FM2 socket compatible CPU (which we list above).
The memory you buy is largely dependent on the Motherboard and CPU. You will want to look at number of pins and speed specifically. All the motherboards we recomend use DDR3 memory with 240 pins. The only think you should change up is speed, although this doesn't matter much for our purposes. If you get very fast memory it will simply run at a lower speed if the motherboard does not support the highest speed. When in doubt get a specifically recomended speed.
Power supplies are what provides the power to your motherboard and various other components. Typically the power supply provides cabling to connect the motherboard, disk drives, and accessories such as GPUs. Always get a large enough power supply to power all of your components. This power supply calculator is fairly accurate , but you will want to look up power requirements for each GPU seperately.
If you don't have a spare one you will need a hard drive to install your Operating System on. You can get any cheap SATA "bare" drive, the motherboard will have a SATA port to plug it in and the power supply will also provide SATA power connectors. You will also need a CD/DVD drive to boot your OS off of for the first time but these can be harvested temporarily from another PC or purchased for as low as $20
This is what will mine your coins. Normally these are used for high-end PC gaming but the AMD line of Radeon graphics cards is perfect for SCRYPT mining. You will need PCI-e power connectors from your Power Supply to power these monsters but there are also Molex to PCI-e power converters. You will also need to make sure you have enough PCI-e slots on your mother board to connect your GPUs (which we explain above using the extender trick).
The best motherboard for Scrypt mining is cheapest. Because you can get an AMD A-Series CPU for under $50 we recomend going with an FM2 socket motherboard. The old AM3/AM3+ motherboard/CPUs were great but they are getting hard to find these days.
A lot of Dogecoin users are new to cryptocurrency in general. Dogecoin is great
because it is reaching a wider audience but there are special issues concerning mining dogecoin.
The bitcoin protocol adjusts in difficulty as more miners mine the coin. The bitcoin network changes
difficulty (due to retarget) every 2016 blocks- now, because blocks are supposed to come every 10 minutes
this usually takes about 2 weeks.
Dogecoin is NOT like this! Dogecoin difficulty changes multiple times per day!. This means mining can quickly become profitable or unprofitable depending on the exchange rate. Just something to bear in mind everyone!
Scrypt is a memory intensive hashing algorithm used in many of the so called "alt-coins", bitcoin forks that are using Scrypt rather than SHA-256 which has recently been dominanted by special-purpose ASIC devices. Scrypt should not be vulnerable to ASICs for several years so a Scrypt mining rig built with GPUs should be profitable for at least that long. The first Scrypt coin was Litecoin and many more followed soon after that.
|Coin||Mining Rating||Trade Rating|
|Litecoin||Litecoin is the largest Scrypt coin currently and the first. It made a number of novel improvements upon bitcoin and there are many solid litecoin pools. Our 5 year price target for Litecoin is $100 USD / coin. Mining is currently difficult but there are many great mining pools for litecoin currently. Litecoin has competant and active developers and a very large and active community.||BUY|
|WorldCoin||Worldcoin is a very orgnaized new alt scrypt coin. It features blazingly fast transaction confirmations and a very large pool of currency (256 Million). Our one year price target for worldcoin is $1.00 USD. Worldcoin mining pools are less common and most are fairly new. We think mining worldcoin is risky given this.||BUY|
|Feathercoin||Feathercoin is simply a faster version of Litecoin with more coins in circulation. We do not see any special value with for Feathercoin given that Litecoin and Worldcoin seem to fill this niche. We do think Feather coin could appreciate in value. However we do not recomend buying at this point in time. Feathercoin has many popular mining pools.||HOLD|
|Digitalcoin||Digitalcoin is an Alt-coin featuring a large money supply (200 Million), small rewards and blocks every 45 seconds. We don't see a compelling reason to use Digitalcoin yet and would recomend selling immediately for another alt-currency if you mine it.||SELL|
