So I just bought an Optiplex 980 from the Dell Outlet store for about $579 with 3 yr warranty.
Intel Core i5-650M Processor (3.20GHz,4M cache)
4 GB DDR3 SDRAM 1333MHz (1 DIMMs)
DVD writer etc...
I was hoping to add a descent sized video card into this system and reviewers sugested that mini-tower case 980 had "room to grow". While there is plenty of room in there....now that I have it...I am finding that there is only about 7" of space before the CPU Heatsink starts RIGHT BEHIND THE only x16 SLOT IN THE CASE....YUP HEAT SINK IS BLOCKING THE x16 PCIe slo
As most people know, most descent cards are way longer than about 7".....
Anyone have any ideas or know of a descent gaming video card that I can use with this system ???
I came across the following...that may work http://www.orbitmicro.com/global/pe-flex16r-p-4354.html
P.s. Yeah I know bussiness machine not gaming machine blah blah..etc etc...no bashing please...useful information appriciated.
So i was able to find a Saphire Radeon HD5770 card that would fit.
However my problem is now with the Dell powersupply as it is under powered.
Plus its got some proprietry "mini\micro" 24 pin ATX connector that ofcourse I can't use a regular powersupply with.
I came across a 20pin to 24 pin min convertor that fits...but the system doesn't power on...
At this point I just wana return the darn thing to dell...unless someone has a solution for my power supply upgrade problem. (PSU= OCZ ModXStream-Pro 600W)
I did sorta a find a solution...and I guess the problem is as solved as it can be right now
Here is what I know and what I did to make things work for me...you folks decide if it worth the trouble
Ok so the heatsink is positioned baddly casue of it size so it blocks the placement of nice higher end card; and the second PCIx slot is only x4. Aso you can't use a double slot card as there is obviously no physical space becasue the USB port, NIC peripherals are right where a 2nd exansion slot would be to accomodate such a unit.
So your limitation for a PCIx graphics card for the x16 lane is about a 7 inch long single slot card.
And as far as I can tell (or atleast a month ago when I got mine) the best candiate for this is the PowerColor AX5770 1GBD5-H Radeon HD 5770 1GB 128-bit GDDR5 PCI Express 2.1 x16 http://www.newegg.com/Product/Product.aspx?Item=N82E168... (Currenlty $20 cheaper than when I got it)
Now you run into the problem of your powersupply just not being enough....And ofcourse Dell's propriatary 24-Pin Micro-ATX motherbard connector....
Some of you might have already guessed where I am going with this
Anyway, the KDM HP-24MINI will not work as Dell used a propietary pin-out on the 24 micro-atx power connector on the motherboard. They were atleast kind enough to stick with the standard cable color coding for the wires.
So essentially I cut of the 24Pin Male connector from the KDM HP-24MINI and cut the female end from the "24-Pin Female to 24-Pin Male ATX Power Supply Extension Cable " and used the Dell Power Supply Pin Out to create my own (soldered the wires per the pinout) "Dell 24 micro Male to Standard 24 Pin ATX Feamale" connector.
Doing it this way I didnot need to splice my OCZ-ModX 600W power supply cables.
The custom conenctor works great. If you have ever worked with wires doing the above shouldnot be a problem. Just makre sure to follow the pin out correctly for the DellMircoATX to StandardATX conversion. Have been playing Warcraft3, Prince of Persia: Forgotten Sands and now StarCraft-II all at maxed settings wihtout any problems (Win 7x64) and the card hits about 70'C at high loads.

Sorry but I don't think I can upload an attachment here.
The "Pin assignments" are essentially those pins that I connected together in my custom adapter. For exmaple Pin 1 from the Dell needs to be connected to Pin 3 (+3.3V) for the standard Power Supply. Pin 15 & 19 from the Dell both get connected to Pin 11 (+12VDC). Send me a note and I can email you my color coded excel sheet.
