Run 2 MoBo in one case? PC & Linux server?

Specs: Windows 7 / ? Linux, 4 gig (7)/ 512M (Serv)
Hi. Thanks for your time.

I propose two Motherboards in one case. I have this nice little Windows 7 machine. At least I thought it was until got home and opened it to find it had so IDEs or PCI slots that didnt already slot essential gear. They wired in no spare slots. Two SATA plugs. Also the PSU is maxed out (I assume. only one more plug left).. BUGGARS..There went the hopes of doing what I wanted with this "cheap" computer

Anywho. So I trolled about the idea of making a nice headless server made only of drives. Then I found this motherload of a case. BIG old refurbished IBM office tower from the early 90's. Houses a P3.

This would solve my problems. with regard to running cables all over the house.
Heck I'll even probably try and disassemble my linksys and mount it there too.
I paint trains for a living, so refurbing this plasic monstrosity will be easy for looks.

My question ultimately is; Any forseen problems? I want to run my 7 machine paired with a P3 Devul-Linux or uMbatu, over a dissassembled Linksys router.. 2 PSU. One case

Might just as well put the two motherboard and two PSUs in two separate cases. and stand them next to each other.

All you are going to achieve by putting everything in one case is increase the chances of everything overheating and nothing working.

Lots of potential for problems but if you want to undertake the project then more power to you.
1. you will need to keep the two system electrically separate. Separate powersupplies, separate front connectors. Do not cross molex connections from one set of peripherals/drives to the other.
2. Manufacturing suitable mount for the second motherboard.
3. Cooling/airflow
4. Add in a KVM switch so you need only one Keyboard, Mouse & Monitor. It's easier to administer the server this way than by running remote admin over your LAN.

Consider instead a good motherboard that supports virtual machines. It would be a better solution.

Why did it take me over a year to phone in a problem to ATT?

Virtual machine's need the host to be powered on, no? I'd like the server to be on a simple on/off switch. If it is headless (no keys or monitor) it could just exist.

Thanks for the warnings about heat. The server should stay cool, I'd be more worried about my windows7 machine. Do you think airflow should be enough to keep this thing from melting? or should I do more than install case exhaust fans

Luckily, I couldn't switch over parts if I wanted to.. Server takes IDE, and 7 takes SATA

Only you can tell whether airflow will be an issue. It's just something to consider when you design/build the additional mounts for extra powersupply, motherboard etc.
In general you want cool air intake low at front and hot air exhaust high at rear.

The fact that you bought a PC without knowing what was inside it makes me wonder how computer savy you really are?

Do you understand the logistics involved in placing two boards in one case? Defintely not an easy undertaking by any means. If anything, you will need a completely customized case with two areas to mount the boards, two I/O areas, two power supply mounting locations, & either two slot areas for add-in cards or a common slot area that can somehow be shared, not to mention enough space for all those HDDs. The case will either have to be over 3 ft tall so that the boards can be mounted one above the other, or over over 1.5 ft wide so that the boards can be mounted facing each other. If the 2nd method is used, one board would have to be mounted upside down.

You'd be much better off ditching your idea & just using two separate cases.

Tech Savy? meh. Sale sir. $250 Cdn w/LCD Monitor..

I had a few of those thoughts cross my mind...The MoBo's, I intend to mount them opposed and offset. The server wont have any cards really, everything i need is onboard already. It's just gonna be wired to all them HDs. There were bays for 3.5 & 5" floppys on the top front. I'll never use them so thats where I intend to put the HDs. Mount the 7machine properly, and raise and offset the server. I'm just going to make my own jumper cables for everything like LAN and such. I even have a spot for my wireless linksys picked out inside..

Any ideas about a Linux O/S that I could run headless (without keys/mouse/video; after setup).
