The case for my first DIY build, recommended by Ars, was the
Antec Performance II SX835II. I ordered it on October 29, 2003 (thanks NewEgg order history), and in went an Abit NF7-S rev. 2 and a Barton 2500+.
Last year I purchased a good-condition SX835II for about the cost of mid-upper tier case (I'm still looking for a reasonably-priced NF7-S). I bought it on ebay from a general seller that must have stumbled on a load of these beloved, arch-ribbed cases, for they had original SXs, SXIIs, and Chieftecs, with and without front panel doors and in all sizes. I haven't seen any computer cases from them since, let alone Antecs. I'm guessing a local tech enthusiast said, "Hey, you have an ebay business, could you offload these for me?"
The last company I've seen use the design is Ultra, but only for part of the bezel. The interior layout is completely different, and the build quality does not look as good. PPCS (I'm not affiliated with them in any way) has
just one more for sale.
