Having srtipped the wee thing completely I had to decide on what mobo and psu to use. For the mobo I settled fo a 113066 cognnc 20000412 mobo socket 370 with Pentium III installed. If anyone has jumper info on this mobo they can pass on to me that would be great. I've searched a couple of hours with no luck at all apart from a spec sheet from a site selling second hand mobos.The mobo apparently is out of an eMachines system. I can not remember stripping one of those at all. To get every thing in the case (mobo hdd, fdd, psu and optical drive) I have to modify all the various original housings so it would all fit together with clearance for air flow.

For the psu I am combining two. The guts of one in the housing of another for compactness sake. Output will be 350 watts compared to the original 50 watt psu. I'll have to figure out how the air flow will be efficient enough to keep the components cool in the slimline case.

A bit of welding and panel beating is required to complete this project....😉

Basically cut the whole back portion out of the chassis to allow the ATX i/o blank to fit with some mesh to allow airflow flow.

In the r/h rear piece where the horizontal card bay was I cut a piece of mesh from an huge ugly gamer case I scrapped a few months ago and fitted it with a small fan attached. Depending on how the psu goes I may fit a larger fan.

Drive supports also had to be altered for mobo clearance and fitment in the chassis.

CPU is a PIII 933. Two fans will be attached to the heat sink. The power input will be via the rear of the chassis though a ON/OFF switch I've added. Because the mobo doesn't have any networking built I've settled for a Realtech 10/100 nic and Realtech wifi card. I also have the option of using SATA drives via a pci PATA/SATA card if I want. Oh the choices...😉

Getting the fans sorted and running properly. The small fan on the cpu heat sink verticaly power leads were soldered to the rear fan lead/molex so when power is switched on both fans will operate instantly. The small vertical cpun wasn't turning initially. There was a break in one of the fans retaining arms. A quick application of a hot soldering iron got that sorted out and away it span.

The top temp controlled fan was tested using a 12v m/c battery I use on my motorbikes when I'm playing around with electrics on them instead of draining the m/cs batteries. I used 32 thou lock wire to insert in the top cpu fan to test it with the two leads connected to the 12v battery.

A copy of the mobo spec sheet is attached for those who are interested.

Looks good ! So what pests do you need the can of Raid for ? Or is that some new technique for cleaning metal ??? 😁

Debugging 🤣

To throw at the bloody huge native cockroaches that try to pinch my mid-morning and mid-afternoon snacks. That is more effective that the contents of the can...😉

maybe said to his better half "I want to have a RAID in my new project" and this is what she came back with? 😉

Like the mesh idea to make the rear of the case to look more presentable, never seen that before

Turn them into an army of minions... https://backyardbrains.com/products/roboroach 🤣

Just tidied up the conservatory work area. It's a lot better..

Been going though my modest computer psu hoard for likely candidates to power the wee thing. Select a few I could chop change or alter. Height is a big factor. I've got the outer housing basically sorted out, so the innards and means of cooling are the order of the day.

Also marked out where I can cut some material out of the hdd mount for air flow. Fun fun fun.......😉

A bit more hacking and slashing on the psu case and hdd mount. Figured I'd need to make an opening in the front of the chassis so ai will flow through the psu housing towards the front of the system with the sise psu fan.. Instead of using the original OEM front wiring I'll make up a custom wire arrangement for the hdd led, pwr led and front switch...

Air circulation cut outs done. Time to refit the grills, psu inards drives etc..

The psu I chose to try out with project had a connector to the psu pcb and the wires where not soldered directly to the pcb. I snipped the original leads, removed the pins from the pcb connector then cleaned them up for use with the replacement leads. Soldered the new leads on to the pins and then inserted the pins back in to the pcb connector. Befare hand I mark what side the blue lead was located.....

Sorted psu fan connection out. De-soldered the cpu fan connector off the original OEM mobo. Then soldered the leads of the psu fan connected on the mobo to it. Potted the underneath the that connector with black silicon sealant so the leads dont short out. Now the psu fan can be disconnected/connected with out any soldering to the psu pcd.
