Back in 2002, it was $1600 new with XP Pro. Someone big and corporate appears to be dumping a lot of them so the price is way down. The liquidators are doing the refurb and you can get a warranty. Mine came with 2.4Ghz P4, 512MB of RAM, DVD ROM, 40 GB HD and XP Pro. You can add a video card but Matt shows that the integrated video is Mach compatible. So there are two PCI slots for things like closed loop cards. I just finished loading Mach3, Vcarve, Cut3D, MoI and Doublecad. It all seems to work but I need to kick the tires some more. Now to figure out how to keep the geckos out of it. :-(
I bet that micro ITX packages up very nicely.

I got mine as a company liquidation too. I think I paid $60.00 for mine. I paid $20 for the 17 inch (normal tube) monitor. Oh yeah! I still want an LCD for shop, however. Need to get it up out of the work zone!

I'm pondering the same problem. I'd love a boom arm for the LCD ( and I'd love a touch screen, etc... too ). LCD prices at Walmart and Costco ( my only two options here ) are pretty good so I'll pick one up there with a wall mount kit. PCs are usually pretty happy as long as they get air. I use a trackball instead of a mouse so I don't need much desk space.
Fortunately, I don't have to consider coolants or conductive dust ( metal or carbon ) . Nema 12 enclosures are available for PCs and monitors but they usually cost a lot more than what you put in them.

I finally took some photos today. For some reason my JPG's wouldn’t upload so I changed them to BMP's. Here is the link to the photos. s621.photobucket.com/albums/tt299/BillJenkins/Table – Hold Downs: I recently had 3 T-Slot Tops cut out of Delrin. I had to plane the surface to get my table exact because the Delrin warped when it was cut but I was able to make the bolt holes larger and the top fits perfectly now. I think I will like the T-Slots but I'm too new to know yet. I show pictures of my first hold down methods. One method uses a Shop Fox T-Slot clamp that I took apart. It allows me to push the wood block tight against the part and then I tighten the bolt down and take the shop Fox Cam off the table. In general, I will use a ¼ inch spoil board to protect the top. The top is ¾ inch thick and if I did it again, I would go with either a ½ to 5/8 inch to save a bit more Z clearance. I looked at few other materials but Delrin was the recommendation. Phenolic was another option. If you have other materials in mind, please post a comment. George found the Shop Fox T-Slot clamps and they seem like they will come in handy but the clamp pad is ¼ inch above the surface so you would need to use a small wood piece in between to hold thin stock. Touch Off Plate: I show my simple touch plate which is just a .01 feeler gauge attached to an oak handle that has a pocket on one side to fit the wires and metal gauge and that is glued to a second oak piece to make the handle. I look forward to seeing the high end touch off systems that a few of you are experimenting with. I like the ideas you guys are working on. Cover: This is a $5.00 cheap Walmart grill cover but it works fine. Thanks, Bill

Like the T-slots you had cut, looks like it will make for a quick and easy set up.
I'm still thinking about the RF touch plates, have to order the TX and RX before I start cutting anything, will be using your idea of a feeler gage for the auto Z one. May get something I like but "high end" I'm not so sure of.

Neat, where do you buy Delrin? I need some of that stuff!
Is that thing in your house? Wow!

Hi Matt,
You can get Delrin at a plastic company. I found it locally. It cost $300 plus tax for a 24X48 inch sheet that was ¾ inch thick. If I were going to do the table again, I would go with a 5/8 inch thick piece if I could find it. When The T-slots were cut, it warped some. Enough that the man had to stand on it as it was being cut and I had to enlarge the 1/2 inch holes to get it to fit. It did bolt down correctly and I was able to plane it level. I think I will like the T-Slots but it was more of a hassle than I thought it would be.
My Romaxx is in a storage unit. I wish I had a real home shop but this place works fine for now.
I’m not sure if you were thinking of experimenting with a table top but it’s worth mentioning that the man who used a large CNC machine required an oversized piece because he wanted to cut the 24X14 rectangles out at the same time to make sure the tops were exact. He needed a minimum of 1/8 inch over on each side so I had to specify that I needed an oversized piece. If I remember, the piece I had cut was 24 and 5/8 inches wide by 48. I also found it interesting and kind of strange to me that the man did not use CAD; instead he used Adobe Illustrator and he had to redraw my CAD drawing. He operates a sign company and his machine is 13 years old so maybe that is the reason.
Edit: I should point out that it is possible that a crack could develop. I don't (think) this will happen but I thought I should mention this.
Bill
