My computer is (or was) an HP a6130n. The motherboard that came with it is a micro-ATX, but it seems to have plenty of extra room. So I'm wondering if it's possible it would fit a full ATX board in it. The dimensions of the case are 6.5 x 14.5 x 16. It would be nice if I could find out soon, as newegg has several nice black friday deals, but they are almost all on full ATX boards unfortunately for me.

In a situation like that it's probably going to depend more on whether the case's MB tray has the correct mounts to install a full ATX board.

Full ATX MBs run about 9.6"x12" in size (244mm X 305mm), but even if your case physically has that much room on the MB tray, you'll need the extra mounting holes full ATX boards use. If not you could probably jerry rig something, but you'd have to be careful with hole placement and spacing as far as drilling screw holes and putting in standoffs.

It might be as simple as finding flange nuts to fit the standoff studs if their studs protrude far enough through the MB tray to secure them with nuts on the other side. If you attempt this I would recommend putting a video card in the MB first, securing the card in the expansion slot, then using a small awl or something suitable to tap marks in the MB tray by inserting it through each mounting hole on the MB.

Take care in noting whether the full space on the MB tray under the ATX board is flat before you start though. If it's contoured at all it will seriously complicate if not make impossible such a mod. A decent pic of the MB tray would be helpful for any further advice.

Yep, that's pretty much it, but I wouldn't mount a full ATX board without securing those spots. Just look at your MB tray and seel if you have 3 mounting holes where they're shown in that diagram below where the Micro ATX board would install. If not you'll need to drill mounting holes there.

If your MB tray is flat and all the Micro ATX holes line up with all the upper two thirds of the holes on the ATX board, it would make positioning those three new holes to drill much easier. Just make sure you get the right height standoffs and secure them well.

Most standoff studs should be long enough to stick through the back side of an OEM MB tray far enough to secure with nuts, and I'm almost positive they are M3 size. So what you want to secure them with are M3 flange nuts, or if you can't find them conveniently, just use M3 nuts and washers.

Well I'd prefer to secure them to a factory MB tray if possible... I will check tomorrow if I see any extra mounting holes.

Although I did find one mATX MB (out of 2 AMD ones total :P) that fairly closely resembles the mATX MBs I was looking at before. It's not in a package deal with a CPU, but the CPU in the package was more of a bargain CPu anyway. It was a AMD Phenom x2 925. Leaps and bounds ahead of my Athalon x2 5000+, but not exactly what I'd call good...

Wish me luck finding a good bargain in my price range!

There's nothing wrong with MicroATX as long as you know the limitations going in. Not much room for lots of components on them.

^Indeed. I've got a GTS 250 on my micro-ATX board right now and I've still got three PCI slots to spare.

Actually I was saying how little you can put on them, not how much. If you've got that many PCI slots though, yours must be an older model.

It's not so much what's wrong with the boards a sit is how ahrd they are to find, especially when one is looking for black friday bundles.

Speaking of which, anyone know any other good PC parts retailers besides newegg and tiger direct? (which btw has the worst design I've ever seen!)

Micro Center is pretty solid. They have a retail store not too far from me, which is where I get a lot of my stuff, but their online store is good. I've seen them have some great prices, including lower than both Newegg and TD for some stuff.
