Description

This build was made to be small and portable, and an alternative to purchasing a gaming laptop.

I already owned the CPU and RAM as they were spares from an old machine that was scrapped, this was the basis of the build and why I've got older second hand components.

First purchase I had to make was scouring eBay for a LGA 1155 Motherboard for my CPU which actually took some time to get a decent board for a reasonable price. I eventually got my hands on the Gigabyte H77N Wifi model for £86 which is a perfect fit for what I needed.

Second purchase was the RX 480 which I also got second hand on eBay to cut cost. I go the Sapphire Nitro model which retails for around £200 right now and I got it for £165 delivered. Bargain. With these purchases the build was in full swing and I ordered almost everything else.

The next issue - CPU clearance. The CPU clearance detailed on the manufactures website for the case was only 61mm. This was only for a full ATX size PSU and they had no details on their website for the clearance when using an SFX PSU which is what I wanted to use. So I ordered the next batch of products, brand new this time, which was the Case, PSU, PSU Converter Bracket & SSD.

For PSU choice I went with the Corsair SF 450. I went with this as I'd seen reviews of the Silverstone series of SFX PSUs to suffer from coil whine frequently. The recommended wattage for using my GPU however is 500W, but after doing a bit of research online 450W should be perfect as I'm not overclocking, and the listed power draw on here was only 360W.

Now I had the PSU ordered I could measure the clearance for a CPU cooler. With the SFX PSU in I measured I could fit a cooler up to 85mm high. Perfect, I could fit something beefier than originally hoped. I went for the Phanteks PH TC12LS as it had decent reviews and I liked the aesthetic (not that this is a windowed case anyway).

CPU Fan orientation - I've mounted the fan to exhaust air from the cooler rather than push air into the cooler. I've gone with this decision as I've also got the PSU mounted with the fan on the underside to help exhaust air from the case. This means that air will enter from the front of the case and the PSU and CPU wont be fighting over it and actually compliment each other. Saying this - I've not actually done any temperature tests to see if the other configurations are equal or possibly better. I may do in the future but for now I'm leaving it as is.

The fan intake, 120 VS 140 - As pictured I've got a basic 120 Corsair fan installed, which I found to be rather loud. I had a Corsair 140 Air Flow fan spare which I wanted installed but due to the length of the GPU, a 140 would not fit if aligned with the pre-made screw holes. So my solution... Velcro. I added small tabs of Velcro to each corner and attached it to the case, seems to work pretty well. However the noise isn't much better, it could be it's an old dusty fan or that the Velcro isn't dealing with the vibrations well. I may get a new quieter fan in the future and go back to a 120, or a slim 140 if there are any decent ones available.

Cable Management - The PSU cables that Corsair provided and nice and short, really nice to work with in a case like this. I feel I've tied them up the best possible in the space given. I also used Velcro to attach the SSD to the bottom of the case as I didn't like the mounting method designed for the case. It fits perfectly and I'm happy with it. I did still attach the bracket made for your drives but this was to add some rigidity to the case as it was a bit flimsy without.

Peripherals - I've got a monitor going spare which I'm using, but as this is a portable PC it's probably going to be plugged into many different monitors so I didn't think to include it. For the mouse I went for a nice cheap wireless with an optical sensor, it's definitely on the small side and would be nice to have charging via USB or something as it's a pain to be replacing AA batteries, for £10 though it's great. For the keyboard I wanted to be wireless too, but still mechanical. I found one on eBay which was a nice portable size, full RGB back-lighting, mechanical AND wireless. They're cheaper switches which I'm not quite used to as they do require more force than my usual MX Browns, but for the price I cannot complain.

It is indeed some tight butt hole.

Very nice parts list, description, pictures and...

Kitty!

Enjoy this wonderful build otherwise known as a new warm box for the kitty to lay :)

Thank you! I'm very pleased with the final product.

I thought a Cat picture was necessary! Fortunately he prefers to sit inside the box instead of on the computer!

Thank you! Have a clear image in your head of how you plan to set it up, I did a mini test-run of building this so I could figure out the order in which I'd need to add parts in. For example the GPU would not fit in the case unless the front was clear, but before the GPU was in I needed to put the HD Audio and front fan cable. And make sure you know your measurements of what fits too! Buy piece by piece of you need to so you can be sure of whats going to fit, and do lots of research online if you've any doubts. This is my first SFX build, previously my smallest was an mATX and I think it went quite well!

great progression of photos showing the build and path for cable management, which is really nice for a mini.
I will never understand why the ssd always has to screwed down the wrong way. Why don't the make mounting holes and graphics on both sides??? Anyway, after just building in a mini Metis case, I can appreciate what a nice job you have done. That 3470 will not disappoint you either.

He wasn't optional unfortunately, and does come with a monthly subscription fee to cover food costs. But as he's so soft and fluffy it's money well spent!
