Portable LAN Build

by ThoughtA




This build is intended to deliver high-quality gaming in a small, portable PC that you can take to LANs. With that in mind, a mini-ITX case and motherboard have been selected. A generic term for this kinds of PC is Small Form Factor, abbreviated to SFF.


At this budget, we're running an Intel i5-7500. Any modern i5 will perform admirably for nearly all gaming needs. The i5-7500 includes a stock cooler, so 3rd-party cooler isn't necessary. Since we aren't overclocking our CPU, the stock cooler will be sufficient in keeping temperatures acceptable.


We're using a parametric filter that will actively select the best-priced mITX motherboard with the B250 chipset. Since Kaby Lake is pretty new, mITX pickings are slim, so if there isn't stock in your region, you can check out motherboards with other chipsets. All motherboards in that filter will include at least one M.2 slot for storage. Fortunately, since we are going with a parametric filter, any mITX B250 motherboards added to the site later will be automatically entered into consideration by the filter for the part list. No revisions needed.


We can comfortably fit 16GB of DDR4 RAM, which should provide some nice memory headroom. We're using a parametric filter to choose a 16GB kit of memory within Intel's recommended specifications at the best price.


We're using parametric filters to incorporate an M.2 SSD with at least 480GB. It's often a good idea to download your games prior to attending a LAN, so an SSD with some more space is a good idea. Bumping up to a 1TB SSD for these purposes isn't a bad idea, but to keep the price down, you'd want to consider a 2.5" drive instead of M.2, since 1TB M.2 drives are fairly new and expensive still. Everyone's storage needs differs, so feel free to change those capacities to your heart's desire.


For our GPU, the Nvidia GeForce GTX 1070 is one of the best price for performance cards on the market and an absolute powerhouse. The GTX 1070 will provide a consistent 60fps on many demanding games like Battlefield 1) at Ultra at 1080p, and even 1440p for some games like Shadow of Mordor. For those interested in VR, the GTX 1070 will have no problem playing any and and all applications currently on the market.

If you'd like more room, there are a couple "mini" GTX 1070 video cards floating around. However, we specifically selected this case because it can fit full-sized video cards. Because of this, we've left the filter open to either size.


Our parts are going into the Lian-Li PC-TU200B. This is a rugged case that comes with a carrying handle that will make transportation quite a bit easier. It features 2 USB 3.0 front ports and comes with a 140mm fan on the front. The TU200B can fit video cards of almost any length. Speaking of video cards, the case comes with a really cool feature for a LAN build - a graphics card holder that will help keep it in position in transport, helping to prevent the video card from bending or snapping or other verbs that will make you cringe and keep you up at night.


For our power supply, we're using a parametric selection of a five well-reviewed fully modular units, all of which are 80+ Gold certified or above and can provide plenty of power for this build. These units are all SFX form factor, so they will fit in the case more comfortably. While we can fit ATX PSUs up to 140mm in length, the hard drive cage may have to be removed. This is an option that can save you a little money if you'd like, and the cage is removable, so it shouldn't be too bad if you choose to go that route.

that case looks pretty cool.

I'd prefer something like a Node 202 for a LAN build; it's small and portable and doesn't rely on a gimmicky handle.
