    Hi,

    I only came across this forum pretty recently while spotting Bit-Tech channel on Youtube.
    I was looking how people are customize their PCs now days. And I was blown away by projects quality and advancement. Was attracted to forum by tubless build from nhenhophach which is amazing.

    After seeing other builds I realize that I need whole machine shop in order to make something decent

    So I have started a scratch build I would like to share with you. It wouldn’t be so impressive but some of you may like it.

    Main concept is to make a pc for my kids that I also could use for CAD lessons once a week or less.

    Spec wise we want to run modern games and graphical software, CAD etc.

    Now, pc itself have to be small. We only have very limited space. House we living in is on the small side and it does not look like it will change any soon so have to coupe with it. We have a little space between wall and build in wardrobe where small desk is fitted. Another thing is money it always is ☺️ I’m limited to £1500-1600. So after ordering all part month ago and going over spending limit here and there. Just couldn’t resist that ultra wide screen monitor from IIyama while I was making research what to go for :
    Ryzen 3600 - £154
    Asus B550-I itx -£199
    Crusial BalistiX 3600 C16 - £64
    Seasonic Core GM 650W - £86
    SSD M.2 Samsung 970 EVO Plus 500GB - £99
    Gigabyte RTX 2070 Super -£410
    AIO Corsair H75- £63
    IIyama 34” ultrawide IPS - £400
    = £1475+ deliverys = about £1500 + mice and keyboard at some point.

    There's not much left to play with ☹️ May end up borrowing, which I try to avoid. To add to it I’m also limited on tools, power tools and space (have a little garage that isn’t a workshop) and I’m living on the island witch doesn’t make things easier in terms of availability in hardware stores, plus pandemic madness.

    Let’s jump to build after positive introduction

    After placing that big monitor on such a small desk (W120cm X D55mm) it was looking hilarious with no space for anything else.

    Initial idea was to do small mini-itx case and very basic to cut on costs because it’s hard to get one and they are expensive.
    But as I quickly realise that not going to cut the mustard

    So thinking for about a week and watching tons of small builds and wall mounted pc ideas, I had been inspired by Matt from DIYperks on Youtube and his folding desk build. Perfect for limited space and will fit my small budget if I plan that right. Another thing is this big monitor that never was a plan to buy. My kids are still young and go wild every now and then so don’t want to limit them in terms of “watch out for this and that”.

    Sum up: limited space, limited money, limited tools and work space, make it safe, save as much space as possible, made out of available materials, have fun doing it.

    This build will be a pc desk you wouldn’t be able to tell it’s PC, once its folded. No design plans just old style pen and paper ;) (my laptop is crushing running fusion 360). Also pictures will be a bit crap because of my old phone and my photography skills. I’m new to writing a blog and English isn’t my first language so apologies in advance.

    OK so far I’m about 1,5 week in a building process. And I have an 1-2h a day after work plus weekends.

    That’s what I have done so far:

    Main material is soft wood and plywood.
    It's the only thing I could get in my area.
    B&Q is almost empty and delivery to the island to expensive. IMG_1 (1).jpg IMG_1 (1) (6).jpg
    Idea is to fit monitor and PC in the box together.
    IMG_1 (1) (11).jpg
    IMG_2.jpg IMG_202.jpg IMG_20.jpg
    Monitor moves on drawer runners and it's lifted by linear actuator.
    IMG_1 (1) (14).jpg Stand off for motherboard and vents added. IMG_1 (1) (27).jpg IMG_1 (1) (16).jpg Main shape and rough view before rounding the edges, cuting top in 3 sections and painting to give it more pleasant look.
    That's it for know

    That's a good start. You found some pretty nice wood, (no cracks or knot holes,) You should try to stain and varnish it instead. Paint requires extra sealing and surfacing.
    Also, Welcome to Bit. :D

    Thank you. You run brilliant website and projects here are top class.
    I'm planning to paint the box part white so it will blend in with walls a little bit. And for top part I will use wood dye and will seal it with poly-wax form OSMO only because I have it left over. Did my worktop with it and its looking good.

    Adding spring loaded hinges on both sides for 2 pop up control panels. I think left side PC front panel, right side back lights and actuator control.

    IMG_3-1.jpg
    Flaps fitted and working fine.
    IMG_3-2.jpg
    Managed to sand and prime the box.
    IMG_3-4.jpg

    I also wrapped monitor lifting frame with carbon vinyl.

    My goal is to make this looking and working decent enough just using tools I have got available.
    And make it as cheap as possible. Will include a BOM at the end.

    Made a big progress through weekend.
    Box is painted and ready to start fitting and adding things.
    IMG_4-1.jpg

    I started with vinyl wrap inside. All carbon black. It wouldn't be seen but will make things looking better inside and let me get rid of a vinyl roll which is about 9 years old and take up space in our tight storage.

    IMG_4-2.jpg
    Next morning it was almost ready so I concentrate on top control panels.
    They were still curing after last 3rd coat of sealant but were good enough to be used for fitting.
    IMG_4-3.jpg

    Decided to add actuator, monitor lifting frame and psu at this stage. PSU isn't modular luckily there is lots off space for good cable management and will be placed away from pc components.
    IMG_4-4.jpg

    I didn't have any plans how to make front panels and was scratching my head how to make it. At the end it came out pretty good.
    First some masking tape magic to mark slots and holes for drilling and filing fun.
    IMG_4-5.jpg

    Next part is an engineering master piece :confused:
    Angle bracket, piece of aluminium sheet and few stand offs. MacGyver style.
    IMG_4-6.jpg

    She's better looking from the front face.
    Only things that I have not done and I want is usb c plug. Couldn't find mobo usb c heder cable long enough. May go with male to female cable at some point. Let's leave that as a subject for future improvements.
    IMG_4-7.jpg

    Left hand side the pop up PC front panel.
    IMG_4-9.jpg

    And right hand side led and monitor lifting control panel. Black dot under the rocker switch is IR sensor for light remote. Both side ready now with cables soldered and tested.

    To be continued... ;)

    This is very interesting and looking good so far! I'm excited to see more! Are the pop up panels spring loaded, and what mechanism do you have to keep them up once opened?

    Pop up panels are on spring loaded hinges I believe they are called "firedoor hinges". At beginning I have made a foam padded catch to add at the bottom of the panels so front strip will work as a stop. But after trying everything assembled playing and modifying a spring diameter it looks like it's not needed. Weight balance turns out to be ok and it works pretty smooth just stopping on the back chamfer of the top piece shown on picture below.
    I don't know whether I should leave this like that or not.
    May add more detailed and better pictures later (at the moment it's disassembled).
    I'm working on a catch now. It will be press to open system.
    Would be nice to add a video but don't know how to yet.

    Looking great. :D
    "engineering master piece" -You joke, but I remember seeing that technique used in an old OEM. It's still brilliant. :thumb: If you were a major manufacturer, I'd call it a cop-out, though.

    Now it's time to fit everything and connect as much as possible.
    I attached top bits and made pop up panels fully working.
    Looking messy and it's just a beginning.
    IMG_5-1.jpg

    Cooling and vents.
    I've used velcro tape around the vents and cut my daughter tights as a dust filter :happy: (hopefully she will never notice they are missing) :worried:
    IMG_5-2.jpg

    Everything fitted and tested but still a fair amount of work to do.
    I was planning to enclose pc components with a top cover and s shaped ally panel but I'm thinking now It may be not needed especially if I want to make a covering panel under monitor. Don't know? I will appreciate any opinions on that.
    IMG_5-3.jpg

    And I finished the day with backlight connected.
    IMG_5-4.jpg
    To the next one.

    Looks great - and bigger than I had thought earlier! I don't know if it would need a dust cover on the inside - may actual worry would be a drink spilling down from the desk/table above - maybe put a little moisture cover over the main pc and the PSU?

    I think you are right. My lazy inner self was trying to cut the corners :) I will make a proper covers.
    I try to make this as small as possible with some clearance for internal parts. At beginning was a plan to use a riser cable to sandwich GPU and motherboard and fit that in a tunnel on one side but realized I don't have enough width unless I take monitor of centre which is not an option.
    Hole thing have W 114cm x H 72cm x D 25cm (W44.88" x H28.35" x D9.84") with desk unfolded D75cm (29.53")

    Have been busy for last week and haven't done much.
    I decided last week to assemble everything but it's not ready yet.

    I had my little helpers. IMG_5-1.jpg IMG_5-2.jpg

    That how it looks folded and hidden.
    IMG_5-3.jpg
    And all out.
    IMG_5-35.jpg

    Quality testers :D
    IMG_5-4.jpg IMG_5-5.jpg

    So over a week of use my kids also were using monitor as a TV with chromecast connected to it.
    IMG_5-6.jpg

    Another thing I want to do and it wasn't plan is a pocket in a cover that goes under monitor.
    Pocket will hold the keyboard and mouse.
    IMG_5-7.jpg
    See you soon...

    I really like it! When the desk part is up, how stable is the setup? would a kid hanging on the desk pull it over - or do you have it anchored to the wall?

    Thank you. I have attached desk to the wall with couple wall anchors. Was stable on its own but would fall with a weight on the desk.

    hey, thats nice to see someone else also raising a monitor. i raised two with my ARMAGEDDON project in 2012 to 2016. exactly the same way. its here somehwere too.
    yours is more elegant. i went wild with my theme. well done.
    i raised the keyboard and usb hub too, and,,,,well a whole lot of automation.
